In the menu bar i hit addon manager then click on fsdream and i see GSX in the list i click it and it says reinstall. this just happened to me because i press deactivate so i can re activate it but now i cant find my activation code. :-( but when it use to work I had the gsx menu on the fsx menu bar where you can choose to update gsx and change the settings but it dissappered after i did the standalone addone manager update
