No Navigraph icon in X-Plane 11 Avitab

I have today installed X-plane 11 and Magknight 789 on my new PC. It all worked fine on the old one but machine was too slow.
Now with this set up I cannot get a Navigraph logo on the Avitab (v 4.8) so cannot get charts etc to display.
What am I doing wrong please?

Hi Tony,

Welcome.

You might try re-establishing Navigraph Account. In X-Plane Plugins menu, Toggle Avitab on, select Providers, re Link Navigraph Account. Open Browser, enter your Navigraph details.
