I really need some help from someone who knows how to fix a software installation problem!

I have the PC game Sims 2 and two expansion packs: University and Nightlife. Got Nightlife first, then University and had no problems at all! The I got Sims 2 Open for Business and ran across an astranged error. I installed OFB and it worked fine, but when I loaded the game all of my University stuff was invisible, or unavailable. I exited the game, and to my demise found out something wierd. The game OFB had overwritted University. So now when I click on the University Icon it says Open for Business...WHAT IS GOING ON!!!????

I love the sims. my suggestion would be to uninstall everything and reinstall. If you still have problems after that i would e-mail tech support at: http://thesims2.ea.com/help/index.php?pid=Help

Trust me they will help. They help me all the time
