Frozen zune 80gig 2nd gen, error 5

Hello, i am here in desperation, please help me if you can.
I have an 80gig zune, which has been working fine since i got it new 2months ago. I left it on charge, and then when i came to use it, it had frozen ( 1st time). I looked the problem up on net, so i followed the instructions and did a reboot, this gave me an error 5 - contact support' screen, also frozen. So now i followed the advice given to restore zune device firmware, basically wipe everything (http://support.microsoft.com/kb/927001/), then my zune was stuck on 'no3 please wait' screen & would not switch off or respond at all. So I waited until the zune died, then connected to pc to charge back up, then the error message '5 - contact support' screen came up again, and again frozen. The zune software on pc works fine so it seems to be the device at fault. Please help as i have no idea how to get my zune back into operation and i am missing my music.
Thanks for your time and i am truly grateful for any help.
Best wishes
Brad

Ps, I have contacted zune support & they said its needs to be returned and is under warranty, but then I am told that as I live in the United Kingdom it will not be repaired/replaced as I do not have a USA address or friends or family living there :-(
