Thankz I'll try changing it
[EDIT]
Didn't work 
instead, I got a different error. How ever, i did decide to delete my redpower config file to see if it would generate a working set of config, and it seems that worked
[EDIT]
Nope, never mind, when i tried putting the IC2 jar back in to my mods folder, ERROR.
