I just tried to register today to get the early bird discount. When entering my last name and email, Marketo doesn't recognize me as a customer. When I proceed to create a new profile, it says a profile already exists and to login using this email. It's an endless loop. As a customer since May, I would think Marketo would recognize me as a customer. I'm using the same name/email that's part of my Marketo profile. Are any others having issues with this?
