I transferred iTunes to a new pc and screwed up. I copied what in thought was everything I needed, but now I have music and apps that show up in iTunes, but gives an error that the file can't be found. Is there an easy way to get iTunes organized again? I don't care so much about the missing files, can I get iTunes to update itself with the current files and not show the missing files? Or do I have to go through and manually delete each missing file in iTunes?
