Hi,
have you installed the our/Navigraph AIRAC?
When yes, open the Navigraph Navdata Client again, remove and install rhe cycle again.
This general community folder moving is so nonsens and no one from Asobo/MS has ever recommend this - only in case of an unexpected issue/CTD and than step by step to find out the package where the issue exist but not as a general rule.
Anyway, remove and re-install the AIRAC cycle via our client and all should be ok.
Cheers
Richard
