Try resttetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-3/FAQ-Troubleshooting-Steps/td-p/714/
You won't loose anything. Just make sure to not delete any files and make a backup.
What's your operating system ?
mine is also doing that and i have the sims 3 on origin and when i go to play it it just sits there and does nothin can someone please tell me when im doing wrong?
@Technolove420 Have you tried the solution described on the first page of this thread? Pulling your entire TS3 game folder out of Documents and launching the game again, thereby forcing a clean folder to spawn, often solves this kind of problem. Once you confirm that you can load and play a new save, you can start moving your existing saves and other content into the new folder from the old one.
If this doesn't help, try clearing Origin's cache. You can go even further and completely uninstall and reinstall Origin itself, which wouldn't affect your installed games. Be sure to select "the hard way."
