@kevinbebek, thank you for your reply. The problem for me was I lost all my PMDG aircrafts showed in the MSFS installation manager.
So it was many work to bring all back (complest deistall and reinstall al aircrafts (737-600,737-700,737-800,737-900 and 777-300ER) and
all of the liveries.
Now I'm decide never use GSX Pro / Config until I get a save solution for the problem. But therfore I can't install jetways from new 3rd payware
airports.
Can you explain more information of your problem/solution.
Thanks
