Can't control sub
 

I have the Steam version of Cold Waters, and I've run into a glitch where I can't control the direction or depth of my sub. I can see that the rudder is full right, but my sub keeps steaming straight ahead, no matter which direction I try to turn. Same with the depth. Planes are full down, and I stay at the same depth. I can control the speed, however. I have checked the control bindings, and they're all OK.

Any ideas?

If you have a joystick or controllers plugged in that you use for other games, check their connection or re-calibrate them. Also, try re-seating the connection for your mouse.
