I am doing a flight in XPlane 11 on a Mac. I have the Navigraph Charts app loaded. When I started XPlane I was asked to log in, which I did. That screen remains active in my browser (Firefox). When I attempt to link the charts app to XPlane to track my flight I get a dialog that says it is unable to connect to the simulator. Please tell me what i need to do to correct this. Note… I have screen shots of both the error dialog and my browser screen indicating that I am logged in however I do not see any way to attach those images to this message.
