I have had the Sims 2, Nightlife and University for quite some time now. I recently installed the Happy Holiday, Family Fun, Open For Business, Glamour Life and Pets. For some reason all of the walls are flashing red and black. No matter what wallpaper I try to put up it is always some shade of red and not the original design. Even when I go and try to create a family the walls behind everything are red instead of the usual brown brick. Once I uninstalled everything that came out after Open For Business the problem was fixed. But everything installed after that in any combination gives me the same problem. I know this is not normal and it is very frustrating. Is it a problem with the game, my computer graphics or memory?:4-dontkno
