Joystick problem

Hi,

I unpluged my Joystick from the PC USB port to use it a a mates house. I have now plugged it back in and calibrated it. But when I went on FS9, The joystick doesn’t pull up, or it does but very slowly. I calibrated it again and again and it still doesn’t work. The Joystick is a QZ 501 Predator.

Does anyone know how to troubleshoot this problem? Any help will be most welcome.

Thanks,
Astraeus
