I have a mac book pro and several of the expansion packs and this has never happened before, but I installed the Sims 2 Pets yesterday and it won't let me run it off of the disc. It says I have to run it off of Bon Voyage which my cousin accidentally cracked, and my parents aren't keen on re-buying. So I can't get into the game at all. Does anyone have any advice? Anything anyone could do would be awesome.
