@Urs, Thank you for the update, I no longer get the error
@Dennis, do you mind telling me how you installed Uk2000 Manchester?
It works perfectly for me in the sim but it still shows the default airport in EFB,
I no longer get the error when I run the scenery config on the Data Provider but as soon as i select the airport in EFB i get the Runway assignment warning and it shows the default airport
Thanks
Steve
