The Sims 2 game keeps uninstalling on its own! The Sims 2 keeps uninstalling itself so that every time I go to play it, I have to install it again! I have used the boolproptestingcheatsenabled true cheat or whatever it is, but I don't think I've ever clicked "force error" (I thought that particular cheat might be the problem). So I'm wondering if anyone knows what this might be from. I also hadn't played it in a while, but last night, I went to play it and it uninstalled itself again. I went to install it, but it won't let me because I can't use the serial number on the back of the box! It says it's already in use.
