Tonight, I got the same Error Msg.---->>> Warning - DefWndProc (isConnected=true): Exception from HRESULT: 0xC000014B
During what was turning out to be a perfect flight in PMDG's 737NGX, after about three hours, the sim appeared to freeze. I say appeared, because the clouds were still whizzing by the window, but I was no longer able to select views, FMC, etc.
At the time, I was running P3D, PMDG738, ASN and Aivlasoft
After hitting the "A" and "S" keys several time with the hope of "unlocking" whatever may have been locked up, the system just totally crashed.
Does anyone know what may have gone wrong?
