Game Help:Wizard/Loading Sims

My Sims 2 Nightlife game is working perfectly... until i click Pleasantville. There are weird paper objects with words and red X's on him and it overlaps everything. Secondly when i go to Create A Family it loads but when i get to Create-A-Sim it completely crashes and a window pops open saying something about the Sims shutting down with an X and an OK button. I've tried everything:

Moving Folders to the Desktop Patch downloads Renaming the folder Uninstalling and reinstalling numerous amounts of times. Going to every neighborhood. Going on a different account on my computer.

I really need help and it works on my friends computer just not mine.I have the computer space for it also.
