It's no use. I think I'm returning the Zune for a refund.
I actually already tried your suggestion. The Zune tech support couldn't help me. They finally said I should try re-installing XP.
What?! Just to get a DAP to work? I suspect that the release of the 2.3 software was packed full of bugs, but I didn't expect the tech to admit that.
Oh well.
Thanks for your suggestion, but getting this thing to work should not take a couple of day's worth of hairpulling in frustration. I'm returning it to Circuit City for a refund. Thank god for their decent return policy.
Maybe I'll look at something else like an Archos, a Samsung P2 or an ipod touch.
