I redownloaded GSX but when I go to the Community folder I see:
XboxGames>Community>AddonManager>MSFS>Fsdreamteam GSX Pro
This Folder is Empty
Just uninstall al GSX related stuff then removed the addon folder... after that use the latest universal installer form FSDT and reinstall all the stuff, also when couatl isn't started automatically you can do it manually after a sim start ;-)
That worked here local :-) Make sure to run couatl.exe as admin too..
