Okay, so yesterday, I inserted my Sims 2 disc into the drive, and I waited for it to load. I get to the "select a neighborhood" part and...there are no neighborhoods to select, but I can make a custom neighborhood. I figured something was wrong, but I wasn't sure what, so I went ahead and attempted to create a custom neighborhood. Well, it worked fine. I went to create a family and the game crashed. I looked down at the toolbar and it said that one of the game files was corrupted.

Today, I uninstalled it and then reinstalled it. However, the same problem happened.

Could this be because of some Sims 2 stuff I downloaded (hair meshes, eye color meshes, clothing meshes, etc) or is it simply a problem with the game (it never gave me problems before yesterday)? And if it's just a thing with the entire game, is there a way to fix it?

Help please I depend on the Sims 2 to keep my mind off of stuff.
