Hi, I am unable to transfer my updated limewire library to itunes and/or my ipod. When I have been successful, it'as been entirely by mistake. I need someone to expalin to me how to do it, smoothly. Thank you!

Are you talking about using Limewire (LW)? If yes, then ignore the LW playlist you see in iTunes. That's simply a playlist & the actual songs still remain in your LW downld folder. What you need to do is add the song files to iTunes music library. To do this see the many techniques here How to transfer music to my iPod (& iTunes)

And to access your downld folder easily & quickly: Go to your LW Library window, select Saved Files folder & press the Explore button. Sample image here: Using Library Explore button to access downld folder (click on link)
The default location of the LW downld folder is: C:\Documents and Settings\"your account name"\Shared

Some how my itunes music is gone and the only place i have it is on my ipod. how can i recreate a music list on itunes and then transfer new music to ipod from limewire?

Check your iTunes Music Folder. Search & find it on your computer. See what the folder size is. You may need to re-add the files from that folder. You could open the music folder, select all the folders & drag & drop them to the iTunes Library icon at the top of the playlists whilst iTunes is open.

If the iTunes music folder is empty. Then you may need to get the iPod files copied back to your computer & add them to iTunes from there. See the above link in my first post & look for reverse iPod near the lower posts of that thread.

(I have been getting the impression that with apple adding different extras to their newer version iTunes that some of them are causing problems / side issues. Your iTunes music list might have been corrupted.)
