Re: game won't start (files corrupted) sims 4
Try moving the Mods folder out from the Electronic Arts folder and paste it to the desktop. Then try running the game again to see if you still get the same issue.
What may be the problem is that some of the mods/cc need to be updated. If that's the case you need to go through your mods folder to see what needs to be updated.
