The problematic program that creates this, is not obviously GSX, but what is blocking it on your system. We'll probably now find out what it is.
Uninstalled GSX and couatl and re-installed again now when in a parking spot I get this message "no airport services are available at this position"
This doesn't have anything to do with Couatl, Addon Manager or anything. If you see this message, it means they ARE working so, please, let's deal with a problem AT TIME, because it can just get confusing.
Virtuali Addon Manager 2.9.0.1 is no longer listed in my addon scenery file.
I'm not sure what you mean with "addon scenery file." Do you mean the "Addons" menu under the FSX menu bar ? If yes, enable the Simconnect diagnostic, to see if it starts or not:
Open Notepad, and copy the following text:
[SimConnect]
level=normal
console=1
RedirectStdOutToConsole=1
OutputDebugString=1
; file=c:\simconnect%03u.log
; file_next_index=0
; file_max_index=9
Save the file as SIMCONNECT.INI in this folder:
Documents And Settings\YOUR LOGIN NAME\Documents\Microsoft Flight Simulator X Files
At the next FSX launch, you should see a text window with diagnostic messages: the FIRST 10 lines or so are important: you should try to note what they are saying. If the text scrolls too fast, use the Pause key on the keyboard.
