To get Pro on your son's machine, use his browser to go to LW's Pro support page at http://www.limewire.com/english/cont...pportpro.shtml

Click on the link about using your email to lookup a new Pro page, and download a Pro for that machine.

As for the iTunes problem, those files are probably on a different machine, and so can't be altered except by the user of that machine. You could edit yours, your son can edit his, but bothof you can listen to each other's.

Cheers
