When problems are confined to a particular channel, it may be that the channel didn't install properly, that it didn't update correctly, or that the installation has otherwise gotten corrupted. A reinstall may fix the problem, so give it a try.
Highlight channel on home screen.
Press * key and choose Remove channel option. [Note: If you have subscribed to this channel through Roku, "Remove channel" will be replaced by "Manage subscriptions". Click this and follow the prompts to unsubscribe from this channel. (Don't worry. You'll still have use of it for the balance of your pre-paid subscription period. You can resubscribe then if you like.) Now the ”Remove channel" menu item will be back and you can remove the channel. ]
IMPORTANT- DON'T SKIP: Restart the Roku to clear its memory. Depending on your Roku model and Roku version number you'll find "System restart" under Roku menu path Settings > System > Power or under Settings > System'. Without the restart to clear the memory you may not get a clean reinstall.
Reinstall the channel. Note it will be added to the END of the channel grid.
If channel requires a login, you may need to log in anew.
If the problem persists at this point, it typically means the current version of the channel app has a problem that must be addressed by the channel itself as they are the ones that create the Roku-compatible version of their app and provide it to Roku.

Re: TennisTV won't open - loads then clicks back to the main Roku screen.
Nothing yet from Tennistv.. they make it almost impossible. I'm trying to find a phone number." I have heard that there are other streaming devices that can't even download the app. TennisTv has to fix it on their end.
