Hey, MoshChic, next time be sure to start a new topic and not bring up an old thread that doesn't relate to your question. (This one is about
InTeen not working.)

You might have an incompatible object or clothing mesh that requires an EP that you don't have. Try moving your "Downloads" folder to your Desktop and running the game.
The best advice I can offer is to test all of the custom content that you've recently installed either individually or in small groups by doing this:
1.) Move the Downloads folder back in the C:\My Documents\EA Games\ The Sims 2 folder
2.) Move your custom content to a separate folder on your Desktop
3.) Gradually add the custom content back into the Downloads folder like suggested above, running the game again after each group until you find the problem file(s).
Hope this helps. :angel:
