I just recieved a new Triple Dragon. It had no image so I uploaded the latest 8 MB full image and the latest Beerman image. I'am using the reciever for Dishnetwork USA. After loading both images it gets all the preview channels but the rest are all black. I figure it needs keys updated. I have read so much and find nothing on this subject. Is there a read me to learn about updating the N2 keys? Any help I would appreciate. thanks
