This weekend I sat down to watch “Argo” using the Amazon app on the Roku 3. When I attempted to purchase and watch the movie on Amazon Instant, it threw an error on the screen. I could still hear the audio, but the blue and white error that said “HDCP unauthorised. Content disabled” error took up the entire screen.
I logged out of the Amazon account, then logged in again. When that didn’t work, I uninstalled and reinstalled the Amazon app. Still, this error appeared on the screen.
Fortunately it was still easy to solve this problem. I simply reset the Roku box by unplugging it, then plugging it back in. The next time I attempted to watch the movie, it worked just fine.
I believe this happened because I switched the Amazon account I was using. I had recently switched from my own account to my girlfriend’s because she had Amazon Prime. I think the Roku gets confused as to which account is in use if you purchase a movie on Amazon Instant, and causes this error message to appear.
Hopefully Roku and Amazon get this fixed soon. For now, just reset it and you should be good to go!
