Hello Umberto
After installation of GSX next level2, together with GSX, and LSZH in Prepar3Dv4.2, I loaded the PMDG737NGX in Zürich at gateE26. With CTRL-F12, I called the menue, and asked for boarding. I get a green bar, telling how many passengers have been boarded, and in the cockpit, I can hear the cabin crew, giving a welcome (like in the old GSX). Never saw a van with the pilots, and the cabin crew, Also no passengers in the jetway.
Both GSX and GSX2 is active in the Addon manager. I have Window7 Pro installed.
Can you help me with this problem? Thanks
