The ntdll crash doesn't have anything to do with any of our products. And in fact, it might be the *cause* of the Couatl.exe crash.
Try to enable logging in the GSX Settings page, restart FSX and then post the Couatl.LOG and Couatl.ERR files you should see in your %APPDATA%\virtuali folder.
I just tried to enable logging and as soon as I did, I got this crash. Im going to restart and try again.
