Hi can anyone advice me as to what to do ? I have the PMDG 737 600 through to the 900 and all was well until my desktop had a really bad day I thought that I had sorted everything out but now when I am running FSX or though the PMDG aircraft seem to be in the flight sim aircraft file they don't show up in the list of aircraft in the choice of aircraft when you want to change from say the default 737 to the PMDG 737ng they just don't show up in the list . can some one please tell me what I have done wrong or messed up my most sincere thanks to all who read my post and even more to those that try to help me
many thanks
