Confirmed,
Uninstalling, reinstalling from FSDT website, reinstalling AM from FSDT website and try actually works sometimes, but sometimes it wont work (GSX) Ctrl+Shift+F12 wont do anything....
My major problem is more with customization of the gates. Sometimes you can customize normally, but there are several times when after clicking on the Customize button, it wont pass to slew mode, the Gate customizing window remains active even after clicking on the "Key guide window", which should lead you to the GSX editing slew mode, ...but ...after that, it just wont load and the gate customizing window remains present. GSX and Coualt remain present at P3D menues, but Coualt is not restarting at all, not even the cache option works, and after that you wont be able to use GSX, this is: Ctrl+SHFT+F12 wont open GSX anymore and once you got out of the gate customizing window you can not acces to it again neither until next sim restart....
All for now, no more clues to find out.... Tested in KMSP, KLAX(Completely unusable customization) but also smaller airports with lite or default graphic load, always same thing, sometimes it work, sometimes it wont... So you are flying Long haul and arrive to gate but, sometimes GSX works, sometimes it wont....
Cutomization became important to me because vehicles positions are not correct and you cant see the marshaller because its inside the buildings as default
(even in payware sceneries like KLAX, KMSP, several incorrect positions), and you want to configure few gates to use more often, otherwise, GSX looses all sense...
