I had this problem too. There is a small plastic ring around the home button, if you remove it then it should fix the problem. If you can't find it, take a toothpick and place it in the middle of the home button almost parallel to your iPod and slowly push it to the edge of the iPod. Immediately after you pass the home button, it will ge under the ring. You will think it is your screen protector, but it is not.
