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.
When it is a problem with a single channel, I'd suggest removing and reinstalling it. Use this procedure:
1. Highlight channel on home screen.
2. Press * key and choose Remove channel option.
3. IMPORTANT- DON'T SKIP: From home screen, Settings > System > System restart. This assures no remnant of the old installation remains in the Roku's memory. It may or may not make a difference, depending on what's causing your problem, but it's worth doing.
4. Reinstall the channel.
5. If channel requires a login, you'll need to log in anew.
Note that the channel will be reinstalled as the last channel in your Roku home page channel grid. You may want to relocate it to a different position (highlight channel, press remote * key, choose Move, use arrow keys to position, press OK to lock in).
