Your problem is not caused by any of our products or GSX. Yes, I can understand that, just because you see a crash report from Couatl.exe, you are assuming it was the cause but in fact, it's the victim of it.
You said you had a Crash to Desktop and Couatl.exe, by definition, being an external .EXE, CANNOT (not even in theory) crash your sim. Only an in-process .DLL, like an airplane Gauge for example, can do that.
So, the crash log only indicates that, your sim crashed to the Desktop ( it would have crashed anyway ), most likely because it exhausted its memory after a long flight, and BECAUSE of this, the sudden shutdown made Couatl.exe to crash, most likely because it was never able to receive message from the sim announcing a shutdown so it could shutdown itself properly.
