Msfs pmdg not in database

Hi, just reinstalled MSFS 2020 today, installed PMDG 737 and opened up Navigraph for MSFS. It installs perfectly without errors but when I try to enter any airport on the FMC I get a NOT IN DATABASE error. It happens with any airport.
Any suggestion on what might be happening?

Hi Teo,


This might be a PMDG ARPT_RWY.dat issue. Please see PMDG 737 - "Not in data base" - #2 by Gatorhawk.

Otherwise try reinstalling PMDG 737.

Please let us know how you get on.
