iFly 747 "lock up"

ARGGH!!!
After two successful VOR to VOR flights from KDEN to KSFO.....one day and one night...both times when I hit Esc to save the flights my rig locks up, and there is no log of my flight time
What is going on? The last time I shut down the aircraft, (not exactly as listed in the ops manual) it locked up.
Everything seemed to work fine during flights.....
Do I need to follow the shut down exactly as it says in the ops manual or am I missing something???
HEEELLP! (Now I'm missing two landings, flight time, and night "time")
