When fighting the monsters's inc cacodemon thing in the cave of bad dreams, I somehow ended up with the camera permanently stuck in the "strafe mode" that's meant to be controlled by CTRL making Rayman walk side to side instead of turn and prevent the camera controls from working. I thought it would go away when I beat the level but it didn't and it's still there after I quit the game and load my save file, making the game unplayable.

What do I do to fix this and what caused it in the first place?

EDIT: Deleting the fanmade dxinput dll seemed to fix it but I'll keep the thread open in case it happens again.
