Please start a new thread for your problem. Issues are almost never 100% the same, and it is distracting/confusing to try an diagnose multiple packs in the same thread.

Try installing the Java JDK instead of the JRE.

You have Mo' Creatures, but not the dependency mod Custom Mob Spawner. You have Ender Storage and NEI (out of date), but not the dependency mod CodeChickenCore. You have the OpenBlocks mod, but not the dependency mod OpenModsLib. Your OptiFine is out of date. Your OreSpawn mod is out of date. Your RailCraft mod is out of date. You have the Botania mod, but not the dependency mod Baubles. You have the Computronics and Statues mods, but not the dependency mod asieLib. You have the GraviGun and Morph mods, but not the dependency mod iChunUtil. You have GalacticraftCore and GalacticraftPlanets, but not the third required mod MicdoodleCore. You have the SpiderQueen mod, but not the dependency mod RadixCore. I stopped testing at this point. One of your mods is not for Forge/MC 1.7.10 but for either an earlier or newer version. You will need to go through each mod which isn't obviously for 1.7.10 to find out which one isn't working. That being said, as you can see by all the missing dependencies, you either aren't getting your mods from the authors (where they tell you exactly what else you need) or aren't heeding their instructions. You would probably be best off by going through and re-downloading every mod (along with whatever dependencies are required) directly from the author's preferred distribution channels. This should have the secondary benefit of isolating which mod is for a different version of Forge/MC.

The modpack referenced by your API URL has either been deleted or disabled.

Actually, it was precisely something you were doing... or rather, something you weren't doing. As I mentioned above, your pack settings has a Version Number. This version number MUST be incremented or changed any time you alter your modpack download. Removing the pack from the Launcher and reloading it forces an update.

Your Tinker's Construct and Mantle mods are extremely out of date. Rei Minimap, to my knowledge, has no published versions for 1.7.10. It is conflicting with one or more mods in the pack. Switching to Litemod and VoxelMap_litemod seems to work, even after adding Extra Utilities.

Have you tried a more recent version of forge? (just for giggles).

That's just it. You cannot keep Rainbowcraft nor ZapApples because the mods are not coded correctly. Mods which are intended to run in both clients and servers (SMP) must have their client code correctly "wrapped" because the server does not have the render libraries or functionality. Both those mods are violating that rule and will not function on an SMP server.

Your pack works fine for me. Make sure you are incrementing your version number in the pack settings when you change the modpack archive/download.

@JeroenFL: Always start a new thread, especially when the thread is this old. As for your issue, this is commonly caused by having the wrong MC version selected for your pack in the settings page.

Assuming you are talking about Equestrian Elementals, there is a problem with the pack. The /bin/modpack.jar file is the wrong size. Not sure how you have altered it, but it should just be the Forge universal binary JAR file renamed to modpack.jar. Why do you have GalacticraftCore and MicdoodleCore, but not GalacticraftPlanets? You should not be distributing the /mods/VoxelMods/ folder or its contents with your pack. This will overwrite client settings and waypoints. Client only mods (mods which must be removed to work in SMP): Damage Indicators FPS Plus LiteLoader MineLP_litemod VoxelMap_litemod OptiFine RainbowCraft Waila Harvestability WAILA Plugins ZapApples (this mod "should" work in SMP but does not because it is improperly proxying its client render code) I was able to remove those mods, create a Forge #1272 server, and connect using your client modpack.

You have altered your modpack archive referenced in your pack settings, but have not incremented/changed the pack version number there as well. This will prevent the Launcher from recognizing that a new version is available. One of your mods is requiring ComputerCraft which isn't present. Not sure which mod it is.

Please provide log files and/or crash reports in a pastebin service (such as http://pastebin.com ).

Some of your mods are named in the format ModName-1.7.10.jar. Almost no authors name their mods in that manner. The implication is that you aren't getting your mods from the author's distribution channels/methods. Specifically, CustomNPCs and OpenBlocks. You have the OpenBlocks mod but not the dependency mod OpenModsLib. Your version of CodeChickenCore (1.0.1.8) does not match the version of NEI (1.0.4.83). Get the latest versions of both from the mod author. You have Tinker's Construct but not the dependency mod Mantle. You have CoFHCore and Thermal Expansion, but are missing the dependency mod Thermal Foundation. You'll need to get the current, matching versions from the mod authors. Correct these issues and come back here if you are still having troubles.

@heyhow123: Start a new thread with relevant details about your issue. Don't hijack someone else's thread.

Why is eyemod named "eyemod-EyeOS4.2-1.7.10.jar.zip". You should remove the .zip at the end. Your ChickenBones' mods (NEI) are not from the author and you are missing the dependency library CodeChickenCore mod: http://chickenbones.net/Pages/links.html Your IC2 version is woefully out of date: http://ic2api.player.to:8080/job/IC2_experimental/ You have Extra Cells but not the dependency mod Applied Energistics 2 rv2-beta: http://ae2.ae-mod.info/Downloads/ You have Morph mod but not the dependency mod iChunUtil: http://ichun.us/mods/ichunutil/ You have OpenPeripheral but not the dependency mod ComputerCraft (Open Peripheral is useless without it anyway): http://www.computercraft.info/ You have Tinker's Construct but not the dependency mod Mantle: http://www.curse.com/mc-mods/minecraft/mantle/2215235 Your version of VoltzEngine does not match your version of ICBM. Get the latest versions here: http://builtbroken.com/project.php You should not be using Too Many Items and Not Enough Items at the same time. Pick one, remove the other. One of your mods is generating an error indicating that it's not for the version of Forge you have installed (older/newer MC version). I'm not going to go through every one of your mods. I'll leave you to do that. Way too many of your mods are simply named "ModName-1.7.10.jar". This strongly implies that you aren't getting all your mods directly from the mod authors (since almost no one names their mods that way) and is likely the reason you have an outdated/mismatched mod installed. You need to be more careful about where you get your mods from, and in following the mod author's installation instructions. You have so many mods without their required dependencies or libraries, every one of which is specifically mentioned as required by the authors.

Please provide the API URL for your pack as well.

The only way to ensure you have the most recent, matching, working versions is to: Be familiar with the distribution channels where the author publishes the mod. MinecraftForum? Curse? Jenkins? Github? Custom website? Be familiar with the current "buzz" about the mod. Are people reporting issues in the mod's forum or issues tracker? Are those issues relevant to your pack? Before I get into listing out of date mods, I did notice that you have no config files in your pack. This is always bad, even with 1.7.10 that doesn't get too worked up about IDs. These config files will be generated in your test environment as you assemble and debug the modpack. They should be tuned to balance mod interactions and to stay in line with your vision for the pack. Some outdated mods (non-exhaustive list): Applied Energistics Chicken Chunks Chisel (use Chisel 2) Ender IO Your NEI may be the 1.8 version. Double check that you have the latest 1.7.10: http://chickenbones.net/Pages/links.html Project Red ThaumicTinkerer (over 300 builds old): http://jenkins.nekokittygames.com:8080/job/Thaumic%20Tinkerer/ Those are just some highlights.

A number of your mods are out of date, even for 1.6.4. Update everything to the latest/last versions (since almost nothing is updating for 1.6.4 anymore), specifically including anything related to Thaumcraft.

This does likely belong in Platform Pagoda. Please always provide the API URL (the URL you paste into the Launcher) for the pack so that we may investigate.

What in holy fudge. You have way too much stuff in your pack archive, and there are things in the /bin/ folder I've never seen before. The /bin/ folder should contain one file: modpack.jar . This file is simply the Forge universal binary JAR file renamed to modpack.jar. Your modpack archive should not contain a /asm/ folder. Removing the extraneous files listed above, and fixing the modpack.jar file allowed me to start your pack.

Forge Multipart belongs in /mods/1.7.10/ Baubles mod belongs in /mods/1.7.10/ AE2 should be updated to the latest rv2 version. Almost all mods are including the latest rv2 as their dependency when relevant. A number of your mods are out of date. You have included NEI for MC 1.8. Get the latest 1.7.10 version. Your WaslieCore mod is out of date and incompatible with your Blood Utils mod. Your Extra Cells mod is for AE2rv2 (see bullet point number 3) Address these issues and come back to this thread if you are still having troubles.

If your pack is working fine for other people, but not for you, the issue is almost certainly on your PC. Things one should always try when a pack isn't working when it should: Reset the pack (reinstall from the pack settings menu) Provide your most recent FML log (/mods/latest.log) and your most recent crash report (in /crash-reports, assuming the client actually crashes) in a pastebin service (like http://pastebin.com ). Provide clear, specific, relevant information concerning the actions you take to reproduce the issue. You need to do (at least the last two) EVERY time you ask for help, even in the same thread.
