ive yet to have a total failure, but i often have this same problem. i usually cut off power to my computer, usually my computer is runnin hella slow and it causes the zune to freeze. ive even let it go for three hours once, is was stuck. after i cut power i umplug zune and do a reboot on it. reboot my puter, it asks to run a scan sometimes and the vista os comes back and i start over and it will usually work. sometimes it takes a couple of times.
whats weird is this method is how i got the z4 update downloaded, it froze in the middle, twice. its the method the z4 update was... updated, it stopped in the middle, three times. when i finally got z4 to work, after 3 days. i tried to update my player, and that froze in the middle too. im so frustrated kuz i love my zune sooooo much..... very sad for u compa i hope zune folks notice you!!! gritz
