Did you run PMDG Ops Center to verify that you have the latest version? I don’t know what version is in the marketplace, but it could be that it isn’t the latest. I had to reinstall recently and after downloading from PMDG and reinstalling, I then had to run Ops Center to upgrade to the latest version.
If that doesn’t help, you will probably have better luck getting support if you post in the PMDG forum.
