Morning John, I installed the latest version of FSUIPC as you requested. I normally start MSFS as Administrator however I accidentally started it normally and when the aircraft was at the gate with batteries on and I ran Pilot2ATC it connected straight away. I then went back and started it again as Administrator and when I ran Pilot2ATC it would not connect. Looks like that might be the problem. I have attached the logs - FSUIPC7_prev is the one started without Administrator rights.
The reason I start MSFS as Admistrator is because another of my programs FS2Crew requires that. One of their FAQ's states:
Problem:
The FS2Crew Command Center does not autostart when MSFS loads. I do not see the FS2Crew Command Center (red airplane nose icon) in the toolbar.
Solution:
1. Ensure Microsoft Flight Simulator is run with Administrator rights.
