N4S and Logitech Wingman Extreme Digital 3D Joystick problem

Hi. I have Need For Speed High Speed Stakes and a Logitech Wingman Extreme Digital 3D joystick. When I first installed and used it, it worked fine. Now, The accelerator control does not give full speed and steering axis is funky. Changing settings in dead zone does not help. Any advice? Thanks. -- To reply, remove "nospam" from my address.
