Okay, so I bought the Sims genorations explanations pack, back in like early April, kinda late march. I am having a problem, it was acting all glitchy one day and when I clicked on the icon to play the game it asked if it could make changes to the computer. Next thing I know, it's uninstalling itself. I've tried reinstalling it, but all it does is just uninstall itself over and over again, even when I try to start the game up regularly, only the the standard sims 3 works. I don't know what to do and I'm really getting mad at the game and yes I've made sure all scraps of the expansion is gone from the computers hard drive. I really, really don't wanna have to buy a whole new game right now so please, someone help me.
