iPod Video Center Button is stuck!

I have an iPod video and the center button is stuck..kinda smushed in. I have had this iPod for less than 10 months and I have not abused it or smashed the button in any sort of abusive/hard way...it just all of a sudden did this. I can still get to things on my iPod when I press it, but I have to press the button really hard and it is getting harder to press(it doesn't click when I press it like it used to either) Please, has anyone else here had the same problem? Do you think I should try to fix this with a warranty? If you think I should use warranty, will someone please tell me where to get started...There are so many links to this site that I don't know where to start, a step by staep will be a big help. PLEASE HELP. THANKS!
