Hi All, I've been using the Dish USB OTA adapter on my Hopper 3 for about a month now. A few days ago, the Hopper3 started not allowing me to view any of the OTA channels. Each channel remains in the guide. When I select the channel, the choose tuner screen appears, as if the single OTA tuner was already in use. However, no other receiver is listed as using the single OTA tuner. I've reset the DVR with the red reset button as well as completed a hard reboot. Still no luck. Thoughts?
