from quicktime to mp3 downloading
 

quit all applications including limewire. Then launch Itunes alone. Under "edit" go to preferences. then under the "general" tab, look for "use itunes for internet playback" and press the "set" button. quit out of itunes, and do the same thing again, just to make sure. Then files (mp3's) should once again download as Itune, ready to launch mp3's, and not quicktime player.
