Hi Urs,
Thanks for your response. Please, see in the attached screenshots, how I have the "Folders" section configured either Data Provider and DisplayUnit. The other two screenshots, as you can see, are from Data Provider window while running. Every time I load FSX and click "OK" to set the aircraft to the desired parking gate at the departure airport, the message "A/C position changed!". Is that correct? And while in flight, every time I have to do some route modification (e.g: ATC direction different to flight plan or change of landing runway at destination), when I click "Activate", I got an error message: LOAD_FLIGHTPLAN_FAILED. Whatever I try to change during flight, I got this message.
A bit frustrating. Thanks
