ATV2 won't open Netflix

Lately I've had problems with my ATV2 opening Netflix. It shows up under the "Internet" menu, and even some titles pop up above the menu bar. But when I click on Netflix, the *boop* sound registers but nothing happens.
When I go up above the bar to click on a movie title, it does the same thing.
It's very frustrating. Anybody know what this could be?

I have JB'd it a while ago and haven't updated iOS since. I never use the JB since I can't figure out how to use anything with it. Should I try updating to the latest iOS?

Thanks.

Thanks, I guess I'll just update the software/firmware. Magically though, it started working on its own minutes after I posted this. It does this periodically. So I do the usual, unplug it, let it sit, reconnect it, try re-setting it with the remote yadda yadda yadda. *shrugs*
