I just got Sims 3 for my Mac and it works perfectly up until I actually move people into a house. It will not let me go into the house, play the people, or edit the house in any way or go back and try to move into a different house. It pretty much just freezes on me. What do I do to get it working again? I'm clueless on what to do and I really want to get it working because I having been waiting to play this on my computer for a long time! Can anyone please help me?
