Dodosim 206 and Saitek x-65F

I have suddenly started having problems with my Saitek x65F and the dodosim 206. When I advance my throttles, the collective will not move and though the torque gauge goes up, it suddenly drops back down to idle as soon as I stop moving the throttles. I've uninstalled and re-installed the 206, reset and rebuilt fsuipc.ini, uninstalled and reinstalled the drivers for the Saitek and even as an experiment plugged in another joystick. Plugging in another joystick worked so I'm assuming that there is an assignment conflict somewhere. Is there somewhere that mentions joysticks that I can have rebuilt? -Damien
