Move the mods folder to the desktop. Delete localthumbcache.package file in the game - important! Fix the game in Origin. Origin/Library - right-click on TS4 - option "Repair game" You have to wait until Origin will fix all packs, not only the base game. Turn on the game to create a new, empty mods folder and check if a game is working now without mods and CC. If it does not work then try doing a factory reset as described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199
