Simlink - Impossible to Authenitificate


I do not know if I am in the good section of the forum but for a few weeks now I am not able to authentificate wiht SimLimk. I uninstall / reinstall the software but nothing changed.

I attached the log :slight_smile:

I suggest you start from scratch with latest Charts and Simlink . Please disable any Antivirus and Firewall.

In Simlink Plugin Settings uninstall Simlink plugin from your FS , then completely uninstall Simlink and Charts using Windows Programs and Features exactly as under .

If they exist delete directories
c:\Users\username\AppData\Roaming\Navigraph and c:\Program Files\Navigraph

Then download and install latest Simlink and Charts Desktop using the default prompted locations.

Restart computer.

Please let us know how you get on.
