This has happened to me twice now, the first time was yesterday when I had downloaded a lot of mods and the game was fine, once I used OpenIV to install something (forgot what it was), the game files got corrupted when I loaded it up. Now, when I used OpenIV to try and install realistic gun sounds, the games files are corrupt again. I don't want to delete all my mods and go through the journey of reinstalling all of them again.. What do I do?
