I solved my own problem! I went to Netflix customer support and they have error 1006 registered as an ISP problem. I changed the channel on my router and did a few other things to now avail. Then I got on the Nook helpline and erased and reregistered my device. Now Netflix appears to be working again. I still don't know what the problem was, but for now it is working.
I did this too with chat support and it worked.
We first tried "resetting the programs". This was done by going to "Apps" and checking for updates. When that screen came up, I then held down the power button until the thing turned off (ignoring the prompt about powering off). This didn't work.
Then, went on to deregister and re-register the device. This will delete any downloaded material or side loaded material you have (I alswo took out my microSD card per the IT support's recs), but not any of the books purchased through Nook. Went to Settings, then Device Info, then Deregister.
Took about 5 mins top reset, afterwhich, re-registered, setup wifi, and then logged into Netflix.
Thanks for the info.
