The MP3 player versions from California are a trip I plug to my windows 7 n it installs but nothing happens can't click to see whats stored. I go to device management n it shows it's plugged in but can't access it. I got me a partition program and not even that works. I'm at my limits here also just this morning I noticed if u turn on the MP3 player n hold the power button until it turns off keep holding n the screen lights up. Im not going to get to a computer for a while I'm too busy right now. If doesn't work turn on the MP3 player n hold the power button ull see what am talking about. I messed with the federal version of this type n well there not the same model. Alrighty then thank you for taking a moment of ur time to read this.
