Having trouble watching a video on my iPhone?

I recently upgraded to iOS 6, and so far it's ok, except for YouTube. I have the downloaded version, and it sucks. I hate it. I've been trying to watch a music video, and every time I tap the video, a box shows up saying "Not available to underage users!" And my account clearly states that I was born in 1989. What's wrong with it! I hate the new YouTube! Is there any way I can get the old YouTube back?

I believe one could backdate their iOS with that. Not entirely certain though so this is more of a suggestion as to how to start rather than fix your problem.
