Character spins whenever I move mouse (Have not found any fixes)

[Leonin]

Every time I try to play Amnesia my character will spin around when I move my mouse. I currently am trying to play in non-fullscreen mode. In fullscreen mode my mouse will be stuck in the corner and I will have to reset my computer. In non-fullscreen mode I can select games and load them but when gameplay starts my character spins. I am able to move my mouse though when I alt-tab in non-fullscreen mode but in fullscreen mode my mouse is always in the corner. I have tried re-downlading the game, updating my audio drivers, updating my graphics drivers, plutomaniac's fix, disabling spyware and firewalls, changing settings in-game, and disabling steam overlay. I found no fix when I checked the troubleshooting guide. Can somebody tell me what I am doing wrong? Also if I didn't provide enough information I would gladly provide more, just tell me.
