My Apple ID Password doesn't work on IPOD

I reset my AppleID Password and it works here for example and works on my computer when I log in to the Apple ITunes store but it won't work if I try to use it on my IPod Touch. I keep getting the pop up box that asks me to enter my password. I enter it carefully and it still won't accept it. At one point it asked me to "Accept the Terms and Conditions" and I did that but it still wouldn't accept my password. I was trying to update the games and other programs i have on my Ipod Touch. Seems I can't access the ITunes store from my Ipod. Seems that Apple doesn't want my business because I can't find a free way to get assistance from Apple. That is strange, especially since it relates to accessing their store.
