best total war game ever

Keep corrupting my legendary difficulty single save files CAddy

I played this game a bit some time ago and then it stopped working. It would crash on start, it would hang up on install. Finaly, I got it reinstalled after removing it completely form my PC. Now that it starts up, all the options to play a single player campaign are grayed out and I can find practically nothing online that will help me fix this. The same advice always comes up. Verify the files. Reinstall the game. Delete specific folders in specific places in the game files. Nothing works. It seems to be a very common problem as I can find people all over with it, but nothing they suggest has fixed in on my PC. Incredibly frustrating. I think I will give up and delete it for good this time.
