Hayu app unavailable on Telus Optik

I have not been able to access my Hayu app through Optik in several days. Today the message says "sorry, the application you have tried to access is temporarily unavailable. Please try again. Error code: 0.  In the last 2 days I was able to start the app but as soon as I selected a show to watch, I would get a message saying it was having problems acquiring the license.  I have tried rebooting the digital box.
