Which version of Pro did you buy ($13.95 with no updates or support, $21.95 with 6 months of updates & email support, $34.95 with 12 months of updates & email support)?

After you bought Pro, you should've recieved an email from LW with a link to your personal download page. Have a look for that email... then you can just use the download link

Maybe you lost the email? Providing that you bought either the 6 or 12 month option & you definitely paid LimeWire LLC - send a PM to limenathan & explain what's happened. Click on this blue link: limenathan (click on link)
