I don't think that PC's time settings has anything to do with it. I have to login to navigraph every hour or so via a320 configurator otherwise my session kind of expires and I can't browse charts any more. That's so annoying especially in the middle of the flight... Please help :d
Same problem here, on long hauls my session gets expired and I can't browse charts anymore, so frustrating, I can't reload a plane during flight I'm in VR inside the cockpit high above the clouds! c'mon folks.
In file as_a320_a321_prof.xml:
BasePath="SimObjects\Airplanes">
What if my installation folder is: D:\FSim\P3D_Addons\0_Aircraft_Core\Aerosoft A320-A321 Professional ?
Now Application start after Mark's advice to place xml file in Products folder.
However I can't see any of the Aerosofts provided paints...
