Cannot see world map detail background

Hi
Normally I have no issues with navigraph charts. However, as of late, everything works fine except that I can see my route, but not the background map. Upper and lower airways show fine. It seems to be a blank page in world map mode except for the route and waypoints. In settings, it says error when updating ver 7.1.33 The chart mode is set for standard IFR. And there is an error message 403 failed to load resource. Can anyone help?
