Thanks for the post.
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 and sign into the channel with your account credentials.
Does this resolve the issue you are seeing? Please keep us posted.
Thanks,

Exact issue and nothing works. Reinstalled channel, restarted ROKU, called WWE (No help whatsoever) Emailed ROKU... No help either. Canceled, then kept subscription. Nothing works. If I push subscribe, I imagine I will be double charged. I giess that is the end of WWE for us.
