Thanks for the report!
From the crash log, I can see that IC2 Classic is trying to access JEI's internal classes and it is crashing.
Please report this issue to them, they should not do that.

i think they just now fixed it with a update that came out a few hours ago

ok i all ready reported it sense i was not sure if it was a jei or ic2 issue
