Alright I did a complete reinstall and patched to 2.01, I no longer get an error, however it instead doesn't even start the game. I hit the "Start Edain Mod" and the launcher closes and the game doesn't start.
I turned off the mod, but the normal game wouldn't start either, so I uninstalled the mod and the normal game still would not start, so I uninstalled RotWK and reinstalled and patched it again, and it worked fine.
Then I reinstalled the Edain Mod and (Not surprisingly) the same issue happened. The game won't start now.
