We are still trying to understand if it's best to set Windows 8 Compatibility On or Off for the Couatl64_MSFS.EXE file. With all my tests, it's best to disable it, but in the previous update (when we set it as Disabled by default), many users said with Windows 8 Compatibility enabled, it was crashing in mid-flight, so we set it back on.
Try setting it back to disabled, which we'll probably do automatically on the next update anyway, since now we have the auto-restarter app, it shouldn't matter if it crashes during flight.
