I am not with Laminar Research or Sim Innovations; just a flight simmer.
This forum relates specifically to X-Plane software problems.
As Air Manager is a 3rd party add-on to X-Plane, my suggestion is to contact Sim Innovations in the first instance for a possible solution. I am confident they can provide/find a solution to your problem. My dealings have always been with Ralph and the responses have be quick. Rus Barlow has been doing a lot of work in the development of the latest version of Air Manager, particularly version 3. The starting point to lodge your problem is at https://siminnovations.com/support/support-ticket
As another alternative have a look at the Air Manager (Sim Innovations) forum at https://siminnovations.com/forums/ for a possible solution.
Hope you get a solution.
