Hi Tony,

Welcome.

Given yours is the only report, this suggests an issue on your machine. I shall assume you also have Simlink installed

I suggest:

- See [FAQ - Simlink Install and Systray](https://forum.navigraph.com/t/faq-simlink-install-and-systray/58)
- In Navigraph Simlink Plugin Settings, for your FS entry press Uninstall Simlink.
- Use Windows to uninstall Simlink and Charts
- If they exist delete folders:  
c:\Users\username\AppData\Roaming\Navigraph\Simlink  
c:\Program Files\Navigraph\Simlink  
c:\Users\username\AppData\Roaming\Navigraph\Charts c:\Users\username\AppData\Local\Programs\Navigraph Charts
- Download and install latest [Charts](https://navigraph.com/account/downloads/charts).
- Download and install latest [Simlink](https://navigraph.com/account/downloads/simlink).

Please let us know how you get on.

Cheers  
Ian
