map display not working

i have Garmin GB discoverer 50k loaded on my Edge 800, this used to display on Garmin Base camp for route plotting

However, now only the INTL standard basemap shows.

The GB discoverer map shows under the list of devices when connected to the pc but the map display remains INTL standard.

The only change i have made is installing the latest 800 update, ie 2.20

Am i being dumb?
