Please Help..Wheel Support

I Have a Logitech Driving force gt which I cannot seem to get to work. I’m pretty new to pc racing games and just got the wheel to try things out but I cant get it to work. In the settings I tried selecting the Logitech wheels but they all say not suitable with my wheel. The default setting works but the shifter doesn’t change gear and after a minute or 2 the wheel wont turn, it becomes very stiff. Any help much appreciated.
