Yes, this just happened to me. Did you find a fix? I turned it in to EA support and have not heard anything back from them except that they are "working on it." I am using macbook pro too. I also posted in the problem in the community forum and no one has answered me yet.
After I installed my Sims 3 , I installed my World Adventures expansion pack. However, there is always have a problem when I start the game. It always said I have error with my installation and I can't play my game.
Installed Sims 3 ambition on a computer without adequate video card...never opened. Now can't download onto a new high powered adequate lap top with the same disc. Can you only load it once? from a particular disc? Will I need to buy another game for the new computer? What do you think? thanks
RMiller if you registered your games with EA, you can put it on a new computer. You can actually install it on 5 computers at once if you want. If you still have your unique serial number you should have no problem.
