CAS crashes and won't change sim
 

I recently downloaded Sims 3 Pets, and everything was going very good. It loaded Apoloosa Plains ok and my game easily opened CAS. But when I tried to begin to name the sim, edit it's body, and change the sim, nothing would happen. It would stay the same default sim that popped up. I even tried changing to a different sim, but when I did it continued to not change the sim when I tried to fix it's body mass and other things. Eventually it crashed when I tried to name the sim. Is there anything I can do to fix this?

Try the game problem FAQ.

I have the same problem....I've done everything in the FAQ, and I had no CC at all before I tried a few mods over at NRaas to see if they could fix the problem.

Iced Blackened Death, can you start your own thread and post your system specs? We also want to know what happened at each step in the FAQ
