Free eMail Digitial Certificate: Error 0x8010001D

Having installed MS Office 2010, I saw upon Microsoft’s website that I could apply for a Free for Personal use eMail certificate from Comodo. Sadly having provided all the details upon the signup page, I’m simply getting an error message “Error 0x8010001D”.

What does this mean ?

Should we be telling Microsoft to pull this recommendation from their Office 2010 list of recommendations for such certificates ? Or is this just a temporary Glitch.

I made the application using IE8.

Thanks
