Hi,my problem is that whenever I need to change the PMDG aircraft from let's say -600 to -800 or -700, and I try to load the next aircraft, FS9 just does a CTD - crash to Desktop.Is this a knows FS9 bug? I can swap between cessnas to pipers etc. but I cannot swap between highend a/c like PMDGs?!!?Had MS not thought about that what they created may support real highend simulations like from PMDG and so has to be able to handle such big aircraft models?!??
