MInecraft 1.6.4 help!!!

Hey guys,

I have a Multi-Platform Minecraft setup. Running 1.4.7 Stable and setting up a 1.6.4 Platform.

When I try to load V1.117 IC2 into minecraft 1.6.4 it crashes. Can someone help direct me as to what is wrong.

I love 1.4.7. (Last release of red power) but there are new things in the updates of the mods I run. However losing red power will kill me.

Anyways back to topic. Thanks guys hopefully we can IC2 working for 1.6.4 Thanks!
