Cannot get last night's episode of American Idol on the FOX site with my COX credentials

The URL I am using is: http://www.americanidol.com/full-episodes

I click on the first video player image (Season XIV Auditions: New Orleans), it brings up a choice of TV providers, and I click COX Communications, then I click a button to sign in with your TV provider, then I get a COX url:

Then I put in my credentials and hit its sign in button.

I am immediately returned to :

http://www.americanidol.com/full-episodes

And nothing has changed. If I click again on the video image for Season XIV Auditions, I am again presented with a screen to choose my TV Provider... it is an endless loop with no feedback anywhere about where the problem might be: with Cox or American Idol.... or with my credentials. But again, I use them directly to sign into cox and see my cox account, no problem.
