I downloaded the FS2CREW voice commander for the PMDG 747-400 on 1st January 2011. Firstly this is an awesome add on to the PMDG 747. I flew about 5 flights following the Main Operations Manual step by step and the application worked flawlessly. On the 6 th flight everything went like clockwork until I ran the Runway Entry Procedure, that went OK and the Main Panel went over to Takeoff. Within seconds this display went to Rejected T/O without any input from me. At this point the Main Panel indicated that the program was in Decent Mode ( flashing star in top left hand corner ). Nothing I tried managed to sort out this problem, scrolling through to Runway Entry again and running the runway entry Procedure again etc. The program still stays in decent mode, whatever you select on the Main Panel. You can ignore the FS2CREW program and fly the 747 up to cruise as normal and you get all the decent callouts in reverse order as you climb up through the various levels. When you come to the Decent piont of the flight you can use FS2CREW from this point down and it works pretty much as it should, sometimes only missing out a call or two on the way down. I reloaded FS2CREW and did a perfect next flight with everything working as it should!! The next flight, however, went from takeoff to rejected takeoff as before. Any ideas?? This is the FS9 version and the PMDG747 has been flying for 6 months without a hitch. Any help would be appreciated. Thanks, Peter
