My browser (Opera) gave me a message that "sensitive" info was to be sent to an unsecured page. I suppose it is obvious I had to choose for "cancel", close that page of yours and give you a warning.
BTW, here is the text of the message (in Dutch):
"Informatie van deze HTTPS-pagina wordt verzonden naar een onbeveiligde pagina op
www.beatport.com.
De gegevens worden verzonden zonder enige beveiliging. Verzenden van gevoelige gegevens wordt ten sterkste afgeraden"
To be clear, I got the message without doing anything, so it gave a feeling of "loosing control".
