I just uploaded Seasons and Pets a couple days ago and now I cannot save & quit without this message popping up: "An unexpected error haa occurred while saving: Error Code 12. Please consult readme for details." I don't have the manual and therefore do not have the readme section. This message did pop up before but then we just started a new game. I have the game and quite a few expansions, and it is running poorly, slowly. Please help.
See this for info on Error 12: http://answers.ea.com/t5/The-Sims-3/FAQ-Save-Errors-Error-12-13-15-16/td-p/652/
