After downloading some qualified Aircraft on line and some qualified scenery library's. Airplanes are there and then the next time they are gone. I get ready to fly and no Airplanes in the flight program at all. I have all the Airplanes in the desktop part of the program but they don't appear when I fly. I have had to reinstall the full program on 2 separate occasions because of this. There must be a way to reload all the Aircraft back to the main flight program so they appear when I go on line to fly. Any help would be appreciated.
