Hello everyone,I was waiting for years for the PMDG 737NGX and now, I'm about to cry....FSX does not load the free flight and crashes and closes immediatly!When I run the free flight, the loading window appears, but remains empty (no progession bar).Then a few seconds later, FSX closes.I do not have this problem with the 747-400, the MD11 or the JS41 that work perfectly.All my other addons work perfectly too ...I do not understand.I uninstalled and reinstalled the 737NGX, but this does not change: Unable to load the flight.I just managed to get it to work twice in fifty attempts.Someone there a solution?In advance, thank you very much.
