When updating the FSNAV database, I have discovered the following:
KJFK, EDDF, CYYZ, and KLAX Simflyers will not update. When any of these airports are checked for updates, "FSNavDBC.exe locks up when any of these airports appear.
KPHL, KIAD, KMCO, KATL, KDFW, EGCC, KEWR and KLAS Simflyers update fine with no problem.
Is this because the problem airports are not in the database, or does anybody have any ideas applicable to this problem?
