How do I activate Hallmark Movies Now on my Roku?

Make sure your Roku and your computer are both connected to the internet.
On your Roku, install the Hallmark Movies Now app from the Channel Store or Hub if it isn't already installed.
Launch the app and click on "ALREADY A MEMBER?" with your remote.
On your computer, go to the link provided for your Roku. If you already have an account, you need to log in before going to the activation link.
On your computer, enter the activation code displayed on your device into the field on the activation screen and click Continue. (We highly recommend using an actual computer and not a mobile device for this step.)
In a few seconds, your Roku will be activated and you will be able to watch and enjoy Hallmark Movies Now on your TV.
