Hello

Who can please help me:
I have downloaded quite a bit of songs via Limewire and I even think I managed to drag them to my music labrary of iPod in my computer (windows). But now everything refuses to upgrade my iPod again. The message I get each time is that the playlists on my iPod no longer exist. Which is quite true as there is no music at all anymore on my IPod, but still everything (fortunately??) including the Limewired songs are in my iPod music library on the computer. Bet I am not the first one with this problem, but have not found a solution yet on this forum, so please, who can help me out? Thanks very much!! Nanda
