No cover art anywhere in Live TV

[Ronstang 294]

I have not changed anything but a few days ago there was no longer any cover art anywhere with anything having to do with Live TV.  On the Home Screen the "Now Showing" is all empty black boxes and when I go to the guide and click on a show or movie there is no art in the description window.

I have no idea what is going on.  I have refreshed the guide data multiple times and still nothing.  I do not know if it is relevant but I am using Channels DVR to watch and record DirectTV Streaming.  It has worked flawlessly for 10 months.
