Recently, I tried running FSX:SE in Windows XP compatibility mode, as I heard that could help performance. It didn't, and actually caused more problems than it solved for me. One of these things was the complete breaking of GSX. After browsing the internet, and trying several different solutions (some tried while still in XP compatibility mode), I am now left with the current situation: I have two addon managers in the Addons tab in the in-game menu bar. The "Couatl Powered Products" addon and the GSX addon are also missing from the menu. I have tried uninstalling by deleting the GSX folder (and even the entire FSDreamTeam folder), and when I re-install, I get not message asking for any permissions to run anything. What can I do?
