Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
Assuming you are located in the US, that channel does appear in the channel store on their web page. If it doesn't appear on your device in that channel store, that usually means your Roku device isn't supported by the channel. Or, if you're not in the US, perhaps the channel isn't available in your location.
