All 30 GB Zunes Expired at the same time!
The normal reboot trick doesn’t solve the problem and Microsoft hasn’t responded to this yet. This can’t happen at a worst time for the Zune support team, as the technical staff is probably all gone for the New year’s eve party.
We never now, if this is a date related problem(and it does look like it), January 1st might solve the problem. Can this be caused by the clock recently implemented?
Let us know if you find something to reboot the device…
UPDATE: The Zune team acknowledged the problem by posting this on Zune.net:
"Customers with 30gb Zune devices may experience issues when booting their Zune hardware. We’re aware of the problem and are working to correct it. Sorry for the inconvenience, and thanks for your patience!"
UPDATE 2 - "FIX IT YOURSELF": Isaac is suggesting that if you unplug the battery of the Zune, you should be able to restart the device. This should normally void your warranty, but most of the Zune 30GB out there are well over the one year warranty period. The detailed instructions are available here. I will personally wait until Microsoft provides a fix for this...
