LSZH not in DATABASE !?

I use the MSFS and ProSim under WIN 10.
I have loaded Navigraph AIRACS version 2208.
Unfortunately, when entering LSZH as the departure airport in the CDU, I get the message: NOT IN DATABASE.

Hi,
That’s not possible - Zürich LSZH is included in the ProSim database. I guess, you have made an installation issue, but the airport is included.

Sorry, that’s not a navdata issue … It looks like something on your end.

Cheers
Richard
