WatchESPN app won't let me re-authenticate, but also won't get me all the content

This morning, my WatchESPN app was working fine. At some point, however, my AppleTV (3rd generation) wouldn't allow me to watch the live stream of ESPN or ESPN2, but other content (ESPN3, replays of older events, etc.) would play with no problem. The message I got said, "Unable to Play Video, We show that you are not authorized for this service," I confirmed with my cable company that my login and password will allow me to use WatchESPN without issue. I then tried logging into the app on my iPad (4th generation) and got the same message. After a few phone calls back and forth between my cable company and ESPN (each referred me to the other), someone at my cable company "reset" my logon ID, and after re-authenticaing my Apple TV device, it began to work. I am still not able to get into the app on my iPad, however, and here is the main issue:

Whenever I attempt to login through my cable provider, it DOES NOT allow me to input my username and password on the logon screen. I select my cable provider, the login screen flashes for a half-second or so, then it brings me briefly to the screen that says "logging you in," then it says "access rights validated," and brings me to the app. It seems to work, but then when I try to watch the ESPN or ESPN2 live streams, I get the same "Unable to Play Video" message and the cycle continues.

I'm HOPING that if I'm able to actually put in my cable ID and password again, it will have the same effect as it did on my Apple TV, but I don't know how to break out of this cycle.

Here's what I've tried already (over and over and over again):

-Log out of the app and log back in

-Went to "Settings" > "WatchESPN" and turned "on" the Reset Authentication" button/switch.

-Deleted and reinstalled the app

-Signed out of my Apple ID, then back in in order to reinstall the app

-Updated iPad IOS software to 8.3

Each time I tried any of the above, it just pushed me through the login process and would not allow me to put my ID and password in.

Any help or suggestions?!?

Thanks
