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 removing/reinstalling, did you restart your Roku between uninstalling and reinstalling? This will make sure there is nothing hanging around in memory from the original installation so that everything for the channel gets reinstalled. It may not make a difference, depending on the exact nature of your problem, but it's worth trying.
