recently I've been having this problem, if i try to add an album or a song to my Zune, it takes a very long time for it to open(from 30 seconds to 3 minutes) and then it only plays half of the song and suddenly sound stops, but the bar for song progression still goes on, and at the end of the song error message comes up "this item is missing or can not be played" and its not just that, my entire Zune slows downe in response speed, its really upsetting
i tied almost everything i could think of, i deleted everything from my Zune and re-synced it( it started to work properly, until i added another album) then i copied the contents of the music folder to a different location, and synced from there, but that didn't really do much help ether, so I'm completely at loss of ideas of what to do or what the problem might be
*the same story happens if i add a video
*i have 120GB only 30-something are taken up
