Umberto,
I have all of your USA airports, including GSX and Hawaii.
All I want to know is how to install this update?
Sometimes, depending on the developer and product, you have to uninstall. Other times, the update will just update what code needs to be fixed. or you may have to completely uninstall, and then install using the full installer.
So for KMEM and GSX, how should I proceed............I don't want to screw up my current setup while updating this particular airport and GSX?
Cheers,
Bill Clark
