cInput2 is a third party plugin that I'd not heard of until now. In terms of the general issue of the axis being off center, usually there is a simple solution for that: unplug your game controller, make sure the analog stick is at rest, and plug it back in. Let me know if that doesn't work, but generally gamepads initialize to whatever their centered state is when they are actually first connected. People who reboot with their gamepad sitting upside down often unintentionally mis-calibrate their own controllers!
Anyhow, how are things feeling in the latest version of the game for those who were having troubles?
