Remember, any problem, issue, or error in your game -- or questions related to custom content -- really do belong in the Help section. Discussion is for "how do I do this?" type questions, not "my game is busted!"
Click on the Help dropdown at the top of the page, then choose Sims 3, and see the FAQs there. Make sure that you actually do what the FAQs say, not just read them, if they're relevant to your issue! If you still have problems, please post a new thread in the Help forum. You'll find a link on the front page of the Help FAQ index.
To avoid posting in the wrong section, please read the Discussion Guidelines:

Good luck!
