Corrupted mapwriter config, this happens quite often actually. Just follow that filepath and delete the file (you will lose your waypoints on the minimap).

Yeah, that's what I meant above with "Worked fine after you added a mod?". Just download it here, press the grey download button under the orange download button.

That is because this person is using 32-bit Java, according to this part of the log you took.

Try starting that modpack again.

Put this file in there. https://www.dropbox.com/sh/4s6csoz8i3u50q0/AACHHp3_iD1Uqgs5l1H75I3ha?dl=0 I know, not the official way, but it seems like you cannot do it differently.

Is the folder called 1.2.1? And does it contain config-1.2.1 (.jar-file)?

Do you know how to get into your .technic folder (If not, %appdata%\.technic\)? Head into cache -> com -> typesafe. Is there a folder in there?

Did it work fine after you added a mod? Or was it working as you started? Do you have this problem with any other modpack?

Which modpacks are you trying to download?

Nope, it doesn't, its not even in the pack... I tried using it in creative singleplayer, and was able to let it work with only a redstone pulse. Downside was that the filter didn't want to work, or atleast not as expected.

"The server" Which of the many?

Yeah, so strange that your system barfs all over you when you try to allocate 11 GB out of the 12 GB you have >.> Seriously, you don't need more than 4 GB.

See Pixel10 in Discord.

Re-installing Java isn't going to work if you keep choosing the wrong version. Use Java8u25.

Please go into your config folder, look for a file named "forge" (.cfg file), open it, locate " # Set this to just remove any TileEntity that throws a error in there update method instead of closing the server and reporting a crash log. BE WARNED THIS COULD SCREW UP EVERYTHING USE SPARINGLY WE ARE NOT RESPONSIBLE FOR DAMAGES. B:removeErroringEntities=false" Now set this to true, and try rejoining your world.

Your zip file is corrupted. Try downloading and opening it yourself.

You got the wrong file mate. You needed to press the download button at the upper-right corner of the screen, not download the Deobfuscated version. Unless you are a modder, and I highly doubt that

Download the update for Immersive Engineering (here: http://minecraft.curseforge.com/projects/immersive-engineering/files/2299019 ) This has a patch for your Potion ID error.

Use RF? MJ?

You will in a few minutes. Mainly because you forgot to add Endercore (Required for atleast EnderIO). The bin folder of the modpack you have uploaded on the launcher should only contain the "modpack" jarfile. The minecraft.jar file in your modpacks folder is downloaded by Technic by default, as that is the minecraft version used.

Trump disagrees with you, so he shut down your dropbox link. He told Dropbox they HAD to work with him, so they couldn't deny him. Right? Anyways, that link is not working.

Sorry, we cannot view attachments on here. Please upload your file to www.pastebin.com and give us the link.

Good thing too that you swallowed your pride, because you wouldn't expect this one. You named your forge.jar like the modpack, but this is incorrect. It really needs to be named "modpack". Also, use this file instead of the one you added in your pack: http://ichun.me/mods/ichunutil/ Grab version 4.2.2.

Why does it contain "Mcheli" twice?
