My ipod wont work right! Ok....I turn it on, and that green light stays on, it used to turn off then i hit play and songs would go, but now it just stays there, blinking, i tried even leaving it on for 9 hours, didnt help. i tried reinstalling, formatting, everything, it says the songs are on there too, the odd thing is, the power checker on the back off it only lights up if the pod is off, otherwise it wont do anything, please help><
