No I haven't changed a thing. But will double check when I get home, that the xbox controller isn't checked, I don't see why it would be though, as I don't have one.
Have just started and created a new character, game runs fine, if not a little jerky, the WASD keys work in the menu when selecting menu options, but when I try to move in game, nothing happens, but works fine with the arrow keys...
Running the game in Windows 7 and via Steam.
