I've registered the plugin on 2 different domains and the same thing happens..
It keeps asking for me to register. Even after confirming on the emails and getting the e,ail saying I'm registered.
This looks like a great plugin if it works.
...Just received an email from the support staff and they gave me a url to past in the browser. It works like a charm now.
My guess is that this is the url that I'm supposed to receive after confirmation.
