ScreenPix error message XRE 03090

I received an email from Xfinity saying they added Epix and ScreenPix to my channel lineup but when I try to access ScreenPix I get the following message.     Sorry,, we're having some trouble.

Please try playing this program again, Still having trouble? You may need to choose another program  XRE 03090

I have Premier so I should be able to access this channel, yet when I go online to view some of the ScreenPix channels it says I need to subscribe to them.

What is going on, and what do I need to correct this.  For a few days I had trouble getting Ovation but that straightened itself out, and now this.  It seems I am having one problem after another and it get's frustrating. Please help!
