I just updated my 80GB to the 3rd generation software and suddenly nothing would play. I'd click and click and click but nothing would start playing. Videos, podcasts, pictures - nothing worked. So I Googled "Zune music won't play" and found this forum posting. I tried the reset method posted by matesz0147 and everything is working fine now. Now I won't be bored to tears at work - thanks a million.
