Re: My sims 4 wont open
@476mzdc0jsqa What happens when you try to repair the game? If you get an error, please post a screenshot. And please try restarting your computer just before repairing as well.
I understand you want to play with mods, but I'd also like to know whether you can open the game with no mods present at all, just as a test. So please move the entire Mods folder to the desktop and delete localthumbcache.package, then try to launch it and let me know how it goes.
