Just got the Sling Adapter, connected it, and tried to view TV from the computer. The Dish Online portal says that it can't connect to the DVR, but the DVR (a 722) shows it's online and connected. If I open the Dish Remote Access webpage, I can see all the recordings on my DVR. How do I get the Dish Online to work so I can watch my programs online? I've tried resetting the 722, but that didn't help.
