Just downloaded the new C-130 (with flight deck) and flying my first flight.  I can't turn on the autopilot in the center panel.  Tried using the mouse, button mapping to a Thrustmaster warthogf and the keyboard (Toggle Autopilot Master - "Z") and can't get the pilot switch to turn on.   I autostarted the AC by spawing on the end of the runway.  Is there something else (another switch perhaps) I need to use?
