I have a couple of premium channels that I have purchased, but two days ago, it pops up with a 733 error and will not let me view the them. I checked online and looked at my account and it is still part of my setup. This happened two weeks ago also, but that was because I had ordered it, but it didn't show up in my current setup. Now it does, and I'm being charged for them, but the channels are once again inaccessible. I have reset the receiver several times, but it doesn't help. This is an HR21 receiver. It's connected via Ethernet and the connection is good. Unfortunately, it won't let me remove the channels online to see if re-ordering them will fix this, because thirty days aren't up. Any ideas on what I might do before I give up and call customer no-service?
