I have recently re-subscribed to Navigraph. I use MSFS. I wish to update my AIRAC. I have downloaded the Navigraph Hub, installed and updated all the tabs including PMDG 737-800. However, when I load my 737 on MSFS, it still shows NAV DATA BASE OUT OF DATE. Plus, when i type in any airfield and I get the message, NOT IN DATABASE. What can I do to fix this?

PMDG navigation data is updateable via the PMDG EFB.

Click the 5th symbol down, the disks. You will then be able to update the nav data cycle.

Verify the nav data cycle has been installed via the FMS
