Check your controls for conflicting controls.

Try adding this: http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2387300-say-no-to-id-conflicts-install-anti-id-conflict Also, the thing I'd need from that error is just outside the screen (Its a conflicting Enchantment ID).

Mind pointing me to where you put JAS? I cannot seem to locate it in your modpack folder. Also, have you tried CMS? Its so great and stuff, that you don't want anything else, and I totally didn't read that last line there!!!

Correct IP stated in server.properties?

Go into the mods folder, remove the LegacyJavaFixer-1.0 mod. The person maintaining the pack has updated Forge to the version which has the fix built in, but forgot to remove the mod from the list (this results in the insane console spam).

Rightclick the map.

Because on other servers, you do not have said issue with the garage doors bugging out. It is not on your side, it is on the serverside.

Please provide us with an API url for the launcher so we can check.

That is because all your required folders are in a sub folder, and you included way too much junk. You need to zip the bin/config/mods folders, you can leave out all other folders. Don't zip the actual modpack folder, as that will put the bin/config/mods folders inside a modpack folder inside the modpack.zip (the subfolder) and makes it load without mods or forge.

Garage door crash, this has likely been fixed in Carpenters blocks 3.3.8 (Legends running 3.3.7). So either request the staff of your server to remove the garage doors or wait and hope the Technic team updates Legends soon so it includes this fix.

Likely BedcraftGP.

I was not able to locate that modpack, you got a page like this?

Give the name of the modpack, we can look for it ourselves then.

I'll need a link to the modpack on the launcher then (as in the API url), so I can check the issue myself.

The Rolling Machine requires 50 RF/t to produce rails. A redstone engine should provide the machine with 10 RF/t, so you need 5 redstone engines for it to work.

Change dl=0 to dl=1 and try again.

No. NO. JUST NO. SERIOUSLY NO. NO NO NO NO NO NO NO. Really just NOPE. NOPE. Nope. NEVER, EVER, allocate 15 GB of RAM. NEVER. After you drop it back down to 3-4 GB, try again. You just starved your system of RAM, because if you allocate 15 GB of RAM, it will allocate all of it to the java process, not just increases if necessary. This means that if your system needs to do anything else, like you opening a browser, or a folder, you will be presented with said error.

Hint: Google for "Dimension ID conflict resolving"

JAMI was never updated to 1.7.10. If you saw it somewhere advertised as 1.7.10, that is likely false advertising on such sites to get more clicks. Edit: After removing JAMI, the ID conflicts start. You have Biome ID conflicts, Enchantment ID conflicts and Potion ID conflicts. Good luck.

Well, it's really quite easy, your game is running out of available RAM while starting, and that is fixed by allocating more RAM. In case you cannot allocate more RAM, you would need to install Java8 64-bit, which can be downloaded here. Restart your launcher after installing, and allocate 2-3 GB.

Send the one with from yesterday (as in June 5th), as the one you sent was from May 30th.

Are you sure it is a good idea to combine BetterFPS and Fastcraft?

This log shows that you were able to succesfully launch the modpack, but that it either kicked you, or you left, while trying to join a server.

And then you upgraded to Windows 10. Welcome to Windows 10. Downgrade your java to java8u25.
