Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
The best way to do this is to go, on your computer, to https://channelstore.roku.com/search/getv (click for link),
click on Add Channel,
then go to your roku and the GETV apps should show there. Select it, and it should then show a "link code" on the tv screen.
Take that code, and enter it here: https://www.getv.org/roku
That will activate the service so you can begin watching.
If you have any other questions, just let me know. Otherwise, please take a moment to rate my service as this is the only way I am credited for my time. Hopefully I have earned 5 Stars but if not please let me know what I can do to ensure you are satisfied. I also invite you to contact me directly with any future support needs at http://bit.ly/1QwLxGh and ask for Nathan.
Thank you, ***** ***** a nice day,
