You didn't read what I said carefully enough. Or the links I gave you. You can just go to LW's Library, select the Saved Files folder, then select a file to the right of it. Now press the Explore button. This folder will open up for you. All yo uneed to do is drag & drop these mp3's onto your iTunes & it will import them into its own library. And will also be the Library as listed under the iTunes playlists.

If you mean how to get them to the 2nd comp, then the Explore button will open your LW dwnld folder & you cqan move/transport these to your 2nd comp & drop them onto iTunes.
