So here's the thing. I bought the GOTY last fall, played it for a bit, and stopped playing. Just recently, I decided I wanted to play again, but I had to uninstall and reinstall the game because it started not working. I did all this, noticed it was back to version 1.1.4-something so I decided I should update to 1.2.0416. I downloaded the file and now the following error comes up when I try updating.
"Old File not found. However, a file of the same name was found. No updates done since file contents do not match."
Short of just uninstalling the game and all the mods that I have, then reinstalling, what should I do?
