Quote from GregoriusT

Maybe a Problem with the 4k-Fix from Forge. Use the 255-BlockID's for IC², like in the good old times.

haha wow your a fast replier! thank you. I made it 960 and that seems to work. (my "minecraft_server" was launching from a backup that i made for the server i was playing on so i wasnt changing the right id tag.)

However a small problem i am also having is when using NEI i try to look at a recipe for anything involving IC2 and the game crashes. next time it happens (probably not very long) i will post the crash report.
