I'm not using a Mac. My computer is an AMD 8 Core ASUS Crosshair V Formula Thunderbolt running Windows 7 Home Premium x64 SP1 with Media Center Pro.
It might not have anything to do with the certificate, but I do recall when I run Windows Updates it does update root certificates. Not sure how you might do that with a Mac, but you maybe should give it a try.
It isn't asking me for a certificate. I just clicked the link in the quote, then clicked login in the upper right corner, and I'm in. Smooth as glass.
I am using Firefox 32.0.1
the site just keeps on asking for a certificate
Using chrome, safari and firefox on mac. Asked another person to check the website and for him it was also asking certificate. Websites should be accessible for all browsers.
