Hi …,
Please restart machine.
If no joy, I suggest you reinstall Simlink exactly as under:
Please disable any Antivirus and Firewall.
If you don’t have MSFS, in Simlink Plugin Settings uninstall Simlink plugin from your FS.
Then completely uninstall Simlink using Windows Programs and Features exactly as under .
If they exist delete directories
c:\Users\username\AppData\Roaming\Navigraph\Simlink and c:\Program Files\Navigraph\Simlink
Then download and install latest Simlink for Windows
Please restart machine.
Please let us know how you get on.
Cheers
Ian
