Cannot login Navigraph FMS Data Manager

I’m unable to log in Navigraph FMS Data Manager. I’m getting error ‘email or password is incorrect’. I tried reinstalling the appliaction and changing password to digits/letters only but had no success.
What else can I do?

Hi …,


I suggest a fresh start using exact procedure below :

Please disable any Antivirus and firewall. Uninstall AV if needed.

In FMS Data Manager Settings Unregister Account:

Use Windows to uninstall FMS Data Manager. Specifically:

  1. Press Start and open Apps & Features.
  2. On the right hand side, open Programs and Features.
  3. Find Navigraph FMS Data Manager in the list, select it, and press the Uninstall button above.

If they exist, delete folders:
c:\ProgramData\Navigraph and c:\Program Files (x86)\Navigraph.

Download and install latest FMS Data Manager to the default location.

Please let us know how you get on.


Hi Ian, thank you for your reply
I tried to disable Antivirus and firewall and reisntalling FMS Data Manager but got no luck
I cannot find that “unregister account” button since my settings window looks like the following:

Please try entering your username rather than email.


I tried username. Still the same error.

Please try Navdata Manual Installation.
