Unable to watch my purchases on tv.xfinity.com

I am able to view the title/picture of what I have purchased/own. However, when i go to click on it to actually watch it, the place to click and start watching does not exist.
Just the movie/TV info.

I usually use IE but a message popped up on that saying I needed to watch in Firefox or Chrome.

Note: I have just tried on IE as well, and the same thing is happening there now too. Why can't I watch my purchases?
These aren't new purchases. I have owned them for some time now
