Hi friends,I change my OS system to WIN 7 x64.When I start the MD 11 I set the Brake with STRG+ .,after I push the pedal down and the Lever in the 3 D cockpit is goeing up.Then I give power but the md is not rolling the brake is not release.All the other Aircraft from Fsx are release the brake with CH Pedal. In my old OS System win xp 32 bit I have no error with the CH Pedal. Can anyone help me?.
