Limewire and two ipods

Ok here's the deal. All of my songs are on limewire on a computer upstairs (windows 98) I just got a dell with windows 2000 for the ipods So I didn't know how to get the songs from old computer to laptop. So we opened a limewire and downloaded all the songs again, put them in Itunes and updated the ipod that worked fine until I went to update the other ipod. I think that when I put the software in for hers it did something to the library causing all songs to have exclamation points. How can I get this Ipod updated without downloading all the songs again into limewire (daughter deleted them after she put them on Itunes) All the time I wasted already I could've downloaded by now.Thanks

how do u get them from itunes onto your ipod?
