Hi Kai,
I've been getting quite a few random crahses of AIGTC lately where the program just shuts down without warning.
It happens at various points of the world. On todays flight I was flying from KAUS to KCLT and three times in cruise AIGTC just shut down. Given I was at 37,000 I wouldn't have thought the number of simobjects was an issue. And it occured 100s of miles from each other so there wasn't a single airport that could have been the problem.
Anyway, logs attached in the hope that they make sense to somebody.
In case of crashes like this, the event log from the Windows Event Viewer is also needed. There should be 2 for each crash.
