when you bought liwire you provided your email during the payment. your email account should have a mail from limewire that links to the pro download page. if it works fine otherwise.
use this hyperlink:
http://www.limewire.com/english/cont...portpro.shtml#
nter the email address you gave during the billing process. and it will take you to the pro download page. and one thing if you find the pro page.. bookmark it.. you can use to upgrade limewire for the next 6 month.
hope this helped.
love and peace
