Hi, the flight logger is a great tool, but I have some tricky situation that happened to me a few days ago.
Situation 1 :
I was flying EGLL LFPG, and during the taxi the engines stopped for a reason I don't remember, probably keyboard error ^^.
"DING" flight logger with a message and then crash.
I think the message was a runtime error.
Impossible to restart flight logger with engines restarted, and there was traffic and a coffee addicted ATC so no time to do the logger startup before restarting engine to taxi.
Situation 2 :
During the cruize over the channel my buggy Aerosoft ATR42 decided that I was not qualified anymore to decide what throttle I should put

"I, the ATR42 hereby declare myself independant from the pilot now and will lock the engine power I like whatever throttle is applied".
I threatened it to refuel with gazoil after landing :@ but that didn't work, so i had to stop the engines in flight, and restart them, that brought the plane back to reason, but engines stopped : flight logger stops. And impossible to restart it in flight.
If one day you plan to rework on flight logger, I suggest you do something about it (possibility to have engine shutdown and restart during a flight, in case of fire for exemple, or any failure, that will be implemented in the PMDG failure system of their coming 744, that many people will use I think, and probably other planes sooner or later).
