I've had my 30gb since 07, i mainly use it in the car, plugged into the
head unit. Out of no where one day, i click all songs and random. it skips half of my library and plays 1 out of 12 songs, and it also leaves me a message saying "the item is missing or can't be played." I know for sure the item isnt missing (from my pc, atleast) and, I dont know what to do and the radio sucks. any tips?
