Flashing Red!! I've had sims 2 installed onto my computer for quite some time almost 2 years, a short while after i installed the game, I installed the nightlife. A few months after that, I installed open for buisness. It ran perfectly fine, a little slow, but that's just my comp. Now I installed University and Glamour Life, and now all of the walls and windows/doors flash red. It's really annoying and I've tried painting over, deleting and re-building walls, nothing works. I've heard in the past that you have to uninstall the game and then re-install, but do I really have to do that?
