Hello. I took one look at USkaarj and just HAD to download it, but the problem is, I can't get it to work. I've tried going into community>user mods> and activating it from there, but it thinks that my CD-Key is invalid. I've got a legitimate copy of the game, and all the other mods I have work fine, but i just seem to be having trouble with yours. Any idea what's wrong?
