I've been very busy, so I haven't had time to play Sim since february. Then, these two new patches. I don't know which one caused it, but suddenly, my game launcher won't open. I have all the expansions and stuff packs, except Showtime and Master Suite. It says my Pets (which I use as disk) is "incompatible" with the computer. It's very annoying, because it means I can't play at all. Besides, it means that if new patches are sent out to fix the mistake, I can't get them, because it won't even show the start menu. What can I do?
