I had a pop up for a new/upgraded version of iTunes and selected to install it. Since then, I can only play a few of the 11 songs I have so far. The others bring up a box that asks if I want to "locate file". I had tried to duplicate the songs into another folder and then to the iTunes library. I still cannot find some of the songs and can't get them to play. Help!
iTunes, Windows Vista, Songs on list; won't open
