Files cause runtime error

My files got screwed up but I don’t know if I can uninstall and reinstall without m save files being deleted. Can I do that or do I have to do something else?

Ok, so it’s not a save file problem. It’s one of the graphic files. I just wanna know if I can uninstall and keep my saved game data. Thanks for that though. I will probably need that eventually.

Edit: I figured it out thanks.
