Before I totally uninstalled all PMDG aircraft from my FSX-SE----the only sim running----so that I could install the latest ConcordeX, the MD-11 worked flawlessly. Made numerous flights with it. All in Windows 10 64-bit Pro.
I managed to get ConcordeX to work in Steam, and one by one re-installed the PMDG aircraft, starting with the 737NGX, then the 777, and finally the MD-11. But it is only the MD-11 which is causing Steam to crash with the following error as per EventVwr:
Faulting module path=C:\Steam\steamapps\common\FSX\fsui.dll
Can any one kindly shed some light on this error please, and what is causing it? The 737NGX and the 777-200/300 work perfectly, as do my CS and Aerosoft and FSL aircraft.
Thanks
