Can you list the steps you're taking? I know that sounds silly, but sometimes, when you step it out, it helps identify where the issue is for me, since I don't have direct database access.
I do show you as registered, but from what I can see, the system doesn't show you as having actually logged in, so you're not mistaken there. What I can't tell is where it's failing. My best guesses would be that you weren't using the upper right hand fields, or that there was an issue with the password. It needs to be at least 8 letters or numbers long, no special characters allowed, and it's case sensitive, so any capital letter used when creating it needs to always be used. Finally, make sure your browser has third party cookies enabled, since the site does set cookies.
Bear with us, and we'll figure this out.
