PFE is a work-in-progress so yes, you always have to check you have the latest version which is currently 2.11.1. If the AutoUpdates does not take you from 2.6 then youwill have to use the manual installation instructions posted above... after which the AutoUpdates should start working again. After my next release I will be sending all the necessary files to Aerosoft so they can then update their installer, but soon after I guess it will be out of date when I make another release. This was/is the main reason for our AutoUpdates feature so we can make frequent changes to the software and our users can receive updates automatically.
