I have the latest paid version of FSUIPC and have all my axes and calibration done thru it. The problem I am having is with the brakes. For onevi cannot engage or disengage the parking brake. It won't change either with clicking on the brake handle or thru key control or button control. GSC keeps asking to release parking brake but I can't do it so I can't use gsx pushback. Also the red brakes tag is on the lower left corner at all times. If I press the brake prefers the differential brakes activate and if I just slight press the brake prefers they disengage, the red light goes out and I can move, but if I left up or press too much the brakes engage again. Please help.
