I can’t play videos on Xfinity Streampix Online TV

Hi!
I was going to play some videos on Xfinity Streampix Online TV, but I keep getting an Error 570 message. I tried clearing my browser cache and cookies, as per the error logs’ instruction, but I can’t seem to make it work. I pasted the error log below:
“This video cannot be played.
We’ve experienced a playback error. (error 570)
Please try deleting your cookies and browser cache and refreshing this page. ”
Any help is much appreciated!
Thanks guys.
