After a couple of years with no issues, one of my Roku sticks gave me this error. I followed all of the steps that I found on another website ( the HDCP Error Detected troubleshooting page on here does not work ). The steps did nothing. I replaced the Roku stick and within a week I am having the same issues again. I NEED HELP. I'm tired of wasting time and money on something that doesn't work.
If ROKU replies with the standard "Please see the HDCP Error Detected Page", I will freak
I don't know why Roku's support always directs me to some other language, but I've come to expect such things from Roku's web team. Anyway, I found it here:

Hopefully there's a suggestion you haven't already tried.
