Worked for me also. Thank you so much! I was getting very frustrated. I think FS2Crew should put out something to all users on this issue and fix.

Tried with Firewall off, no change. Question: I just installed Pushback Express for MSFS. When I installed it, the installer showed an install option for P3D. Will Pushback Express install and function in P3Dv5.3?

I have used several different aircraft, both default and add-on. I also changed my GeForce Video Driver back to the prior one since I had just updated it a few about a week ago but that didn't help. When P3D freezes I have normal aircraft sound for a while but a short time after that the sound goes away. Then it just sits there with the black rectangular popup that displayed in the middle of the screen as soon as I clicked on UGCX. When I decide to click on the screen, it greys out and P3D says "(Not Responding)". At that point I can wait for a CTD or close P3D myself.

The first time it crashed was the first time I used it with P3Dv5.3 and I was at an add-on airport. Then I tried it at a default airport with the same result (P3D CTD).

My first install was a clean install and I am not having problems with any other add-on. I see no reason to do another clean install.

UGCX causes P3Dv5.3 CTD every time I try to use it and FS2Crew Tech Support is not much help.
