I'm not really sure what you mean...
Which version of Air Manager are you talking about?

4.1 is an old version.

Never heard about that before. Should be much better than the default 737.

That is the old x737 I believe.
What's wrong with the Zibo?

There's no autopilot that works with the standard 737. The one that does work for X-Plane is for the Zibomod.

And if it still does not work, there might be something in the log.txt
C:\ProgramData\KnobFS\

I'm completely stumped, it works fine here now with your exact script. Which code editor are you using?

Looks like you're missing a > here: "(H:MFD4_SoftKey_KnobInnerPush)"
It has to be "(>H:MFD4_SoftKey_KnobInnerPush)"
I have corrected your script and it works fine here.

This has been fixed ages ago. You are probably using the old GNS bezel(s).

Your database contains various errors. It looks like you've managed to start Air Manager twice, that might have messed it up.

Copying over your beta data is just a matter of copying the content from the beta folder to the release folder in C:/users/your username/
