Hello, Yesterday I suddenly lost all axis controls aileron, elevator, throttle, rudder, toe brakes. I tried to reassign them but no luck. So next I renamed the config file and tried again with no luck. In the axis tab the axis is being correctly identified and the correct number values corresponding to the movement are displayed, but the control surfaces on the plane no longer move. I reprogrammed buttons on the button tab and they work. Also, If I enable controls in FSX -> Settings -> Configuration, the control surfaces move. Can anyone tell me what may have happened to cause the symptoms described or more importantly how to get them back working again? Thanks!
