HDCP problem on Netflix?

Streaming on Netflix has been working for me perfectly fine for the past 2 years that I've had the ATV 2. Now all of a sudden I am getting an HDCP error when trying to finish watching a show on Netflix which was just streaming fine 10 minutes ago.

I've tried all the troubleshootings, from checking the HDMI cable to switching it around. I've also restarted the ATV. Streaming works fine everywhere else, I'm just getting this HDCP problem through Netflix all of a sudden.

Any advice would be greatly appreciated... thanks!
