HiI have done that according to troubleshooting, It is still not working, has anybody else the same problem. I am flying since 12 years the flightsims but never ever had after installation problems like this. I am super frustrated since the PMDG747X is my favorite AC. How can I get it back to fly. The 737X is nice, but I want both....Julian any other option or advise. PMDG has received a ticket with my dll, however still no reponse!ciaoCaptainHoliday
