I have not had any problems with the multicolored rainbow kit problem.
But, after looking and editing the CFG_DEF file, i may have figured out the solution (if no one else has yet).
Open the CFG_DEF.INI file found under \data\cmn with WordPad
Scroll down to the bottom and where it says BAKED_LIGHTING = make sure it says BAKED_LIGHTING = 0
Hope that helps,
Cheers
