I have tried everything and manually deleted all my games, even the registry keys manually. The problem is ,my Sims 2 Fun with Pets Collection which includes 2 stuff packs, will not reinstall. It says all packs are installed, when I try to reinstall off the disc the registry folders for Fun with Pets comes back. I can't think of what else to try except maybe reinstalling the OS but then comes the headache of having to back everything up. Can I put my OS in another partition and leave my stuff alone......aaaarrrrgggh! I contacted EA and they were so baffled they even gave me a free expansion. :suspiciou What would you do? Any ideas would be greatly appreciated!
