Okay, so I was playing sims for a long time, and I know my system requirements are met. The problem was that I was going to the root folder to get some custom content, and while in the folder "c-drive", I noticed that beside the program files, there was "windows". I deleted it, because it wasn't there before, but now the game won't start up at all. I clicked the app icon and it opens for a second, and shuts down. It's really frustrating.
