I have been trying for DAYS (since the release of GSXv2) to get my addon manager back to the Addon drop down in FSX. Initially, after installing, I lost all my previous FSDT sceneries and had to reinstall them. Then lost my GSX & GSXv2 (not on my FSX dropdown). So, then I uninstalled all GSX, GSXvs, and Addon Manager; completed a cold system re-boot, and reinstalled GSX, GSXv2, then Addon Manager. Still no GSX within FSX (I've tried the Ctrl +F12, but that doesn't bring is up either). I do have two listings for Coatul, but no Addon Manager or GSX options.
I must tell you, I am really enjoying your sceneries and really was enjoying GSX and GSXv2! Awesome, when it worked for me.
At any rate, I'm pulling my hair out trying to figure out why I cannot get GSX and Addon Manager back to work within FSX. So, now I'm at your mercy, and hopefully, am seeking you expert guidance.
