I would post this in the newbies section but I'm fairly sure it's not supposed to be happening...

I just got my n810 but can't seem to get it to play even the songs that came with it. I start up Media Player and browse to one of the three sample songs and click on it. If I hit play, the play button is grayed out and the stop button becomes available, as if it were in the middle of playing something. But the play time indicator stays at "--:--", and of course no sound comes out of my speakers. Am I doing something wrong? Do I need to install codecs or something?

Thanks for any help...
