How do I fix my game?
I have the Sims 3 with two expansion packs (Late Night and Generations). I know now that you have to use the disc of the latest exp. pack released that you have to play, but I used to think it was the latest one installed (Generations, which is latest for both). I couldn't find my Generations disc, so I tried reinstalling Late Night, and since then, the game won't open. How can I fix this?
