I have an Imac G3 and after a song is downloaded it is a white document with a blue music note like i said. I was having an issue going on that I was trying to correct so I unistalled Limewire with the uninstall icon thats in the Limewire folder and then all of a sudden now the songs I would download were coming up plain white and i could not launch them in itunes, previously everything was running like a charm. I think it took me 3 times unistalling before I could get them in the itunes format. I would suggest to try again.Are you familiar with the Macsatellite as an alternative? I also use that and it works fine but i favor the Limewire so keep trying Good luck
