EDIT: Alright kids. I do sincerely thank all of you for your help. I don't have enough time to go thru and individually thank all of you, but without your help I wouldn't have even known where to begin. It turns out my nVidia GeForce was TOO up to date. ._. I was running version 191 and needed version 190 since both Sims games weren't compatible with 191. They really thought that one through.
On another note, I won't have internet for awhile thanks to our WONDERFUL wireless provider, but when I do come back, I'll have some pictures of my updated Fused Shadow (from my Midna) and pictures of my latest cosplay costume.

Hopefully everyone will enjoy it.
Thanks again, everyone!

------END EDIT------
I posted this question on Yahoo Answers yesterday, with no luck. I could really use some help - I have no clue what's wrong with this.
My copy of The Sims 3 won't run. I recently ran a destructive restore on my computer, and reinstalled this game (which was working perfectly before). I installed the latest DirectX drivers, and the game ran fine. I changed my in-game graphics settings and quit, but when I went to start the game again, it wouldn't run. After I click "play" from the game launcher, the screen goes black like it's going to load (though the taskbar is still visible) and it stops and takes me back to my desktop. I've tried reinstalling the Sims 3, reinstalling DirectX, and restarting my computer, and nothing works. What should I do??
Additional notes: The Sims 2 also doesn't work, but other games I have (like Spore and The Movies) work. I have an Emachine, and have installed an nVidia GeForce 8400 GPU video card.
PLEASE! I could really use any bit of advice/help.
