Error message XRE-03059

I'm getting an error message when I try to watch any local channels.  It reads:

We're having some trouble on our end.  This channel isn't currently available.  Please try tuning away from this channel for a few seconds and then tune back to it.  If that doesn't work, please try again in a few minutes.

I've restarted the TV box and completed a system refresh, but the problem persists.  HELP!!
