Sometimes downloading random custom content from others on the site isn't really the best idea. I never had download from others, if you did, I would just get it from the store not the exchange. It is best that you should get rid of the stuff you downloaded from exchange and delete those sims just in case it wasn't a virus or something. :/ sorry that messed up your game, maybe downloading from the modsims would be better since it is a bit much better.
