The helpers here are volunteers & don't work for LW

Did you get any emails from LW after buying Pro? You should've recieved an email with a link to your Pro personal download page. Any chance that the email might've gone to the spam/junk folder of your email client?

Providing you bought Pro from the official site Lime Wire » Official Website & Free Download, BitTorrent « & paid $34.95 to LimewireLLC, send a PM to limenathan & explain what's happened.
