Hi, there, Many of us are running Windows 7, myself included. To add to that, my version is 64-bit. Theoretically, if something works in version 8 of X-Plane on the same machine, it should work straight away in version 9 as well. The main thing I gather here is that you mention the brakes not helping to slow the plane. To me it sounds like there is some movable axis on the joystick configured to operate the throttle, but it is not set correctly. Have you set it to work in reverse by checking the check box to do so when in the axis property section for joysticks? You may need to do this, as it sounds like your 0% throttle is acting as 100% and 100% may be acting as 0%.
