Thanks guys but even with only the warthog plugged in, I'm still having issues. Everything still wants to go in a circle. Even in a different game (mech warrior), the mech still just goes in a right circle. As soon as I increase the throttle on any airplane in FSX, the steering in it goes crazy and the rudder goes to one direction or another.
I don't understand what's going on and it's getting extremely frustrating. I would hate to think I just bought a $460 paper weight.
