Please attempt to add an exception at the bottom of the error page. Then inspect the certificate - see the attached screenshot for instructions. Do not actually create an exception for the cert.

Who is the issuer of the cert? Please post a screenshot of the Certificate Viewer window with the issuer information visible.
