Hello Nik,
We are sorry to hear of the issues, we are here to help.
As you have stated that all database references are not found, then it means that something is wrong with the base Aviation Trainer Launcher for installing all databases.
This is not just the navdata, but terrain, obstacles, safetaxi, etc.
The base Aviation Trainer Launcher is the first component that you have installed, not the GTNXi PC Trainer V20.42.
Usually it would be V3.12.1.0 or V3.10.3.0
As a first step, let's try a manual install of the databases. Do you still have the base Aviation Trainer Launcher, if not, download the zip file of the version that you already have, extract it and manually run this file:
https://download.garmin.com/avtrainerful..._31210.zip
or
https://download.garmin.com/avtrainerful..._31030.zip
\setup_resources\databases\3.5.0.0\Databases.Setup.msi
This is an example path for V3.10.3.0
We suggest doing this after a fresh PC reboot. Not to worry, we will get this sorted, we always do.
Best regards.
