Hi Keith,
I notice the picture was taken when the 360 was using Diane's profile. Do the onscreen graphics populate if you switch to the shared (default) profile?
Generally the graphics don't populate when there is a loss of internet connection. This usually also shows up with a lot of TBA's (To be announced) showing in the EPG. This is usually fixed by either rebooting the hub, or 360 box.
The error message (possibly CS9994) when trying to access/play something from Amazon prime was probably connected to a lack of internet connection
Is anything showing under Settings> System > Diagnostics?
