I can't get Pro Sites and Blog Templates to clone a site.

I can't get Pro Sites and Blog Templates to clone a site. When I try to clone a theme it simply doesn't create a new site even though the checkout process says that a new one has been created (password is given, no email sent, no new site created). Also, the link that Pro Sites is giving on the last screen of the sing up process is to the main domain and not the subdomain. Any thoughts?
