These are my controls. I use WASD for movement, N for normal attacks and M for special attacks. It should be enough for you to access the controls menu. Open up your "controls.ini" and paste my controls.
Alternatively, delete your "controls.ini". The game SHOULD revert to the original controls or something.
Good luck.
