I don't know if it's connected, but since loading JFK, I have lost the ground assistance services at all my FSDT airports (KLAS,KLAX, KJFK). When I select Ctrl-F12, I get the option to open hangar doors only. I tried Shift-Ctrl-F12 and get nothing at all. I do not have the GSX full version, just relying on the option in the purchased airports. Any clues?
