I have FSX (not the steam version), I installed the new update to GSX, I loaded up my FSX and acknowledge all the messages. I clicked on the Add-on tab but GSX is not showing up. I went to my Addon manager and shows my GSX active. My KIAH and KORD airports are not loading up at all. I click restart Couatl and nothing happens. Please help. V/R Chris
From your report, it seems you have the Couatl menu (otherwise you couldn't restart it), but you are missing the GSX menu. This seems to indicate that, instead of updating using the FULL GSX installer, as indicated on the announcement and on the release notes, you updated only with the Stand-Alone Addon Manager, which not enough, and it's not what we instructed to do.
The only way to install this update, is to download and install the current GSX FULL installer.
