After you renewed your Pro, you should've recieved an email with a link to your Pro personal download page. Is that the link that you said you went to? Did you buy Pro from www.limewire.com for $18.88?

If you did buy from the official site, have a look through the thread below for links to help. The best bet is probably to send a PM to RSterne (just remember that you won't get a reply over the weekend!)
