I don't know anything about the Display Export App, but this looks like what was happening to me when I was using the Auto Start function. My MFCDs would not power up until I discovered that I needed the "Eng Oper" switches on my TM throttle base set to the middle (NORM) position during Auto Start. Seems if there's no power to the MFCDs, there's nothing to export. None of this may apply to your situation, but thought I'd throw it out there as a possibility.
