[help] CS2 problems

i've been trying to figure out an issue that i've had for a while now...

whenever I use photoshop CS2 (or any adobe suite) with any of steve greiner's tiger skins, i can't use any tools or do pretty much anything. I know how to solve it with exceptions in WB and things like that, but i just want to know what the cause of that is? I can use the skins in PS 7 perfectly fine.
