No charts

[MV Noeta]

I just did the latest software update for my three networked XL chartplotters. Now one plotter will not show any charts. I thought the master may have been switched, and when I did that, I would have to buy new charts.

Charts all show up on the other two plotters and my pc running TZ Pro.

Not sure what to do.
