Hello,
I've noticed a new issue in the past few Addon Manager updates. When I get the addon manager update notification in fsx, I quit FSX and download the new version from the website, then proceed on installing it. However, after the installation is complete, when I run FSX again and start a flight, GSX is not loaded; Couatl menu does not appear on the Addon menu. A reinstall of GSX solves this. However, it becomes an annoyance, especially if I forget to reinstall GSX after addon manager update, then I have to quit FSX again, and load my flight a third time after reinstalling GSX.
