I'm not being able to watch the shows on itunes festival app

So, I'm using my iPhone 4, with IOS 6, and the itunes live app is not working properly here... I'm only being able to hear the shows, even if they're not live anymore.

I really don't know what's going on, but I already tried reinstalling the app, which didn't work, so yeah, does anyone knows something I could do to fix it??

P.S.: Sorry if my english is bad, I'm from Brasil, and oh, just so you know, I was able to watch and hear the Paramore show, but it was the only one, after it, the app just started hating me!

(I'm probably not in the right place to ask this question, but sorry, i couldn't find a better one.
