How do I fix this Zune problem in Ubuntu?

Whilst trying to mount my Zune onto my ubuntu desktop (thus opening it via Wine) I got this for the first time:

“UNBLE TO MOUNT ZUNE
Error initializing camera: -60: could not lock the device”

What the heck does this mean?
“Camera”? The icon of a digital camera appeared on the desktop instead of that of a portable media player.
(By the way I have not yet managed to work with my zune using wine.. I’ve tried and retried.. and this time was just the furthest attempt, but I got this weird message.any suggestions on how to make the bloody thing work?)
