The same thing happened when I tried to configure netflix on my HD+, but netflix works fine without doing it. If I remember correctly, the linking actually links B&N to your netflix account so they can track what you watch. That didn't sound like a good thing to me so I skipped the configure/link option. If you want to do it you can probably find an answer by searching the forum.
The linking doesn't work. It didn't work on Color and Tablet and it seems it doesn't work on HD or HD+ either.
You don't need it.
Just run the app, log in there, and everything works fine.
Thank you, I have no idea what I was thinking. My Netflix works perfectly fine, though I almost never use it.
