Hello,
I am using P3D V4.5 with the hot fix. I love the new update, however, if I try to load any PMDG aircraft, the screen goes to black and is unresponsive. The only way I can get the P3D to close at that point is to use Process Explorer and shut P3D down that way. However, I do notice, couatl.exe is highlighted in purple while P3D is stuck in Black Screen. Any thoughts?
