I have a screenshot of the Limewire site saying "Get PRO special onetime download for $13.95". I clicked on "Get Pro" but then the site wanted to charge me $21.95.

How can I take Limewire up on the onetime offer which I tried to get at the time but wasn't allowed to? I would be glad to be billed $13.95 to purchase the Pro version.

Thank you in advance for your assistance.
