I suggest a fresh start using exact procedure below:
Please disable any Antivirus and firewall.
If you have backups of previous AIRACs you wish to keep, backup c:\ProgramData\Navigraph\FMSClient\backup
Use Windows to uninstall FMS Data Manager. Specifically:
- Press Start and open Apps & Features.
- On the right hand side, open Programs and Features.
- Find Navigraph FMS Data Manager in the list, select it, and press the Uninstall button above.
If they exist, delete folders:
c:\ProgramData\Navigraph\FMSClient and c:\Program Files (x86)\Navigraph\FMS Data Manager.
Download and install latest FMS Data Manager .
Please let us know how you get on.
