I'm having the same problem as slayergal: since using limewire, all of the songs previously purchased from iTunes and listed in my iTunes library (they are still listed in the library...just not usable) give an error when I try to open them ("the song 'X' could not be used because the original file could not be found. Would you like to locate it?") - but I've looked everywhere the "yes" button on the error message sends me, and although I find itunes folders, the songs I'm looking for aren't in them. I even tried. I even tried the suggestions in the reply to slayergal's post, but not being very computer savvy, it had the same result. I'll probably need someone to walk me thru a solution step by step. I'm desparate, as I had a lot of songs in the library. There are still a few things left in my library that are usable, and they all seem to be whole albums that I purchased; individualy purchased songs and songs downloaded from a friend's computer aren't usable. PLEASE HELP!!
