This location not authorized? - DirecTV

I fell asleep watching tv and when I woke up the screen saver was on and when I hit the select button the message I get is "This location is not authorized". Why is this happening? My main DVR box is operating fine, it's just this one receiver. What should I do? I've already hit the red reset button and that didn't help

This question, "This location not authorized?," is about DirecTV channels, programming, equipment, and sports.
