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.
Highlight the channel on the main screen, press the asterisk button (*) on your remote and choose Remove channel. Then go to Settings->System->Systemrestart and Restart. Once it has restarted, add the channel again from Streamingchannels. See if it works after that.
Thanks for your quick response. i will check that. suppose if the channel is removed from a region and the channel is already add to that particular region before its removed from that region, the above issue will occur or not?
