Missing Addon Mappings suddenly

Pulled up the FMS Data Manager today to check something. It no longer has the mapping to X-Plane 11, doesn’t find it in a scan, and when I attempt to add it manually, the addon list is empty.

Also, under “Settings”, it shows I have a Monthly Ultimate subscription, which is in error, I have a yearly FMS subscription.

Any ideas what suddenly went wrong? Have tried uninstalling the FMS Data Manager and reinstalling, no change.


Welcome to our new forum. I show you as having an FMS Yearly subscription. Maybe check on Monday and if still showing incorrectly please send email to contact@navigraph.com

I am not aware of any server issues at our end. Maybe try

Please disable any Antivirus and firewall.

Please use Windows to uninstall FMS Data Manager.

If they exist, please delete folders:

c:\ProgramData\Navigraph\FMSClient and c:\Program Files (x86)\Navigraph\FMS Data Manager.

Please download and install latest FMS Data Manager .

In Settings check you have correct path to X-Plane .

In Adddon Mappings tab, Remove X-Plane 11 entry, press Scan and you should now have X-Plane and X-Plane addons with correct mapping.

Select and download X-Plane and X-Plane addons in Addon List

If still a problem, please post screenshots of FMS Data Manager Settings tab, showing Version number and X-Plane 11 path , and Addon Mappings tab showing X-Plane 11 addons and their mappings.


Deleting c:\ProgramData\Navigraph\FMSClient was the key.

Not sure why it happened in the first place, but looks OK now. Settings screen in FMS Data Manager still shows me as on a monthly Ultimate subscription, but I’ll recheck on Monday and e-mail the address you mentioned if it is still in error.

Thanks for the help!


You are welcome. Glad it is resolved.

Happy flying.
