Where did you buy Pro from? The only official site is Lime Wire » Official Website & Free Download, BitTorrent «

If you bought from the official site, you would have paid either $24.95 for 6 months worth or $34.95 for a year's worth. LimewireLLC will appear on your credit card as the vendor
If you did buy from the official site & have saved your emails, you should have an email from LW with a link to your personal download page. You can download a version of Pro from that link. If you didn't save the email, send a PM to limenathan limenathan (click on link)

If you paid some other scam site for Pro, then your email address wouldn't ever have been in the official database. And you won't be able to download a new version of Pro from the official site.
