Hi…,
Welcome back.
Are you by chance using Addon-Linker ? If so please see FAQ - Recommendation/using Addon-Linker - content.xml file.
Make sure MSFS is closed.
Move content.xml from %appData%\Microsoft Flight Simulator
to a backup location.
Run latest v1.0.5 or later of Navigraph Navdata Center. This should reestablish content.xml in correct order .
Install AIRAC Cycle 2213.
Please let us know how you get on.
Cheers
Ian
