I'm sorry to say that you have "bought" basic Limewire which is available free of charge from Limewire. A pro version is available for $US18.88 which includes six months of e-mail support and some enhansements to the application.
A lot of sites are scamming people like this.
So to answer your question go to this link and get your free Limewire!
