I have the PMDG 737-600/700 and FS2Crew and how ever I try to load the aircraft it will not work. I have loaded from the default C172 and used the PMDG 'Cold and Dark' Flight. Please help. I used to have this excellent product on my old PC but it doesn't work anymore. Thanks in advance, Nick Taylor(G-NICK)

Hi Nick,Try this:1. Don't use saved start-up files; they generally cause nothing but problems. Load the Cessna, shut it down as per the manual, then load the PMDG 737 (Make sure you're in the Cessna's 2D cockpit).That sounds like it should be it based on your description.Cheers,Bryan
