My Sims games 2 won't play at all. I have all of the expansion packs and the one that plays them all is the university life CD, but when I put it in and click on it nothing happens. I can hear the disk spinning, then it just stops and nothing comes up. I've tried restarting my computer, cleaning the disc, I deleted the cache files, I even just let it sit over night and retried it all in the morning. Nothing works. Also I've tried to uninstall it and it won't even let me do that........anything I click on that has anything to do with the game just doesn't pop up. Help? I have no idea what to do.
