Same problem, keep spinning left and looking up. I have no joysticks connected and I disconnected all USB devices before launching the game, then disconnected keyboard and mouse while in game, no change.
I also can't rebind keys, they just revert back to whatever they were before, http://puu.sh/7cf2c.png.
While running windowed, I stop spinning if the game loses focus. Inverting Mouse option makes me spin left and down.
Using G15 keyboard.
