Prepar3d v5 resets

  • Here's my problem. I load up the Vulcan and get her ready for flight and taxi to runway. Give her full throttle and thu der down the runway. Positive rate gear up. Climb to my altitude setup trim etc for level flight then Boom the flight sim restets to default setup on runway in default aircraft at default air base. This problem is only with the Vulcan all other aircraft are fine. The Vulcan is fine In prepar3d v4.5 also. Any advise would be greatly appreciated.

    Many thanks
