Showtime Anytime Not Working with Uverse

I just tried setting up Showtime Anytime through my Xbox 360. It gave me the activation code and the website to sign up on ShowtimeAnytime. But when I choose Uverse in the drop down menu, it says "I don't have Showtime Anytime with my account', which I do. And the odd thing is, I'm not even logged in. It doesn't even give me the option to log in. I tried clicking other tv providers and every single one of them offered a log in screen, but Uverse didn't and just kept reloading the same page that said Showtime is not on my account and doen't give me the option to type in my login information. Is this a problem for others and how can they fix this?
