"Flynet has lost the connection to Flightsim"

[migman29]

I've had the above message pop up on two consecutive flights at about 1.00am,GMT.
Both times flying the same aircraft(into to different airports though),at the same phase in the flight,just as I'm lining up onto the ILS/Locator at about 2000'.

The aircraft was in a steady descent(700fpm@150KIAS).

I then get the Fs error message "Crash-Aircraft overstressed" right after the Flynet error message.

I then check my internet connection and all is fine,I'm still connected.
I check Flynet,myself and the aircraft are at the airport I've "crashed" at but my flight is reset to "booked".
I have to then cancel my "booked" flight and re-book a flight from the airport myself and aircraft are located at.
It's costing me and my airline(Venture Hawaii) a fortune.
