I don't get it, I can install a game and play it through with no problems. But once I remove it from my computer and try to install it again later on, it either won't install at all or it will install but won't play. Anyone ever have this happen? I've tried it in safe mode and even the program compatibility thingy, nothing seems to work. I just tried to install System Shock 2 again and it installs but once I try to start it, nothing happens. Any suggestions?
