Re: HELP, please, had problems with the sims crashing in game (supernatural) and now wont open AT ALL

Uninstall the ones you still have and clean your registery. Then reinstall those. If that doesn't help, you need to uninstall everything and resort to using the download version you can get from Origin for free if you registered your game

Try uninstalling following the instructions here: http://simswiki.info/wiki.php?title=Game_Help:TS3_Uninstall
