Stop working in CAS

So I thought the problems were fixed when my games finally popped up, but now when I enter the game and I play for a bit or when I am at CAS, it crashes and says Sims 3 has stopped working. I redownloaded the version 1.67, I re-downloaded the Ultimate Fix, but I don't know what else I can do. I looked at the crash thread on what to do. I did the Run as Administrator, but it still crashed. Im just at a loss. Im sorry to ask so much, I just want my game back to normal again.

Thank you,

Hello there!

You said you took a look at the crash thread. Was it this one here?

If it is, you should try all of the steps that are on it. Specially, remove the Mods or CC that you may have, and also delete the cache files that are inside the Documents\Electronic Arts\The Sims 3 folder. These files are as follows:

CASPartCache.package
compositorCache.package
simCompositorCache.package
scriptCache.package

Please, try all of the steps on the guide and also delete the caches to see if the problem persists. Keep us updated on how it goes. Good luck!
