Hi c_hazel,
C'mon...lets go to the LW forum! It's not far
If you've deleted your files from LW then I'm afraid they're gone. If you've deleted them from iTunes, you'll have to go back to 'add file', look in your LW saved folder & put them back into iTunes.
Have a look on the LW forum for a sticky (in red) about not deleting files, it has links to a few file recovery programs which might
work.
*Think the sticky's in the Open Discussion section
