Try removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more.
Does this clear up the issue you are seeing? Please keep us posted.
Thanks for the post regarding the issue you are experiencing. I understand that you are unable to stream the Crave channel.
A playback issue may be the result of a network problem, or it may be caused by an outage with a single channel. In some cases, removing the channel and then re-installing it may help. To ensure the process is successful, follow the steps below making sure you restart your Roku device before adding the channel again.
Remove the channel: Highlight the channel tile on your home screen and press Star to open the Options menu. Select Remove channel and confirm.
Note: If you are removing a subscription channel billed to your Roku account, you must cancel the subscription before you see the Remove channel option. For help identifying this type of subscription channel, read the detailed article about removing a channel.
Restart your Roku device: Settings >System >Select System restart.
Re-install the channel: After your Roku device restarts, visit the Roku Channel Store and add the channel again.
Note: If you are adding a subscription channel billed to your Roku account, you will need to resubscribe.
If after attempting the suggestions above, you are still unable to play any titles from a single channel while content from other channels plays fine, contact the customer support team for the channel provider to report the issue and get help.
