If you bought Limewire then the email you received after you paid has an email address to send your support questioins to -- posting in the frum will seldom catch a developer's eye, in my experience, but they respond pretty promptly to email and will carry on an ongoing dialogue until your questions are aswered, if not solved (for some issues there are no solutions).

Why do you need kaazaa to download files? Limewire does that by itself.
