Hello Umberto
Excuse my long unspecified answer.
As once again the problem:
If I call the GSX Menu or at the latest at the push pack, the P3D is terminated due to an error or fatal error.
When I restart the P3D, I see a window with FSUIPC problem. Have it added you.
If the P3D V3 is then started de FDST airports and GSX are not displayed / loaded.
Thank you very much for your renewed efforts.
Best regards
Urs
