Your confirmation email should have included a link where you could download the Pro version. If you have lost or misplaced the confirmation email, you can visit http://www.limewire.com/english/cont...pro_lookup.jsp and type in the email address you bought Pro with, and it will direct you to the page where you can download Pro. All of this is very easily found by visiting limewire.com, clicking on Support, clicking on the big red link that says, "LIMEWIRE PRO CUSTOMER? Click here for assistance", and then clicking on the big red link that says, "Update to LimeWire PRO version 3.6.15."
