I have created and saved an IFR flightplan from KSAN (San Diego) to KDFW (Dallas FortWorth) using high altitude airways. Now it seems the it might work the first time I fly it, I get handed off to departure and and put on a heading of 080 and later advised to resume own navigation which gets me to DFW, however the second time I load and fly the saved flightplan. I get told by departure to fly I heading of 050 and never told to turn to 080, or resume own navigation,. 050 does not take you Texas! Once I figured I'd just fly and see what ATC was going to do. I did this until I got handed to Miniapolas (SP?) center, and gave up.
If I delete and recreate the flightplan it works the first time, the has the same problem the second flight, where I then cancel the flight plan and go visual on GPS.
Has anyone else experianced any similar? I have tried to resinstall flightsim to fix, but no go.
