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.
Something that does not seem to appear in the instruction from the link that you provided is that you may want to take out the SD card first and then plug it back in without the SD card. For some reason the SD cards become corrupted and then cause the Roku to hang up on the loading screen. Well this worked for me. Hopefully it will work for you!
