Have you done all this?
How do I activate TheBlaze TV on my Roku?
After you have launched the TheBlaze TV Channel for the first time, you will be given a code to enter at TheBlaze TV/Roku. From your computer, go to that page and click to Activate your Roku”. If you are not already logged in to TheBlaze TV, sign in to the TheBlaze TVm account that is linked to your TheBlaze TV or TheBlaze TV plus subscription. You will then be asked to enter the code that appears on your Roku Player to register it to your account. If you do not have an TheBlaze TV account, select to Buy and Activate TheBlaze TV.
The Roku Player will automatically update itself after you have entered your valid activation code and we successfully link your TheBlaze TV or TheBlaze TV plus account to your Roku Player. This verification process takes about a minute to show on your Roku Player screen. Now you should be able to access live and archived video via TheBlaze TV on your Roku Player.
I did that....but, maybe I need to do it again, although it does not ASK me for password or code anymore
