Vista - Certificate Revoked Notice on Websites

I am trying to log on to my local High School Districts online gradebook
site, and I keep getting a notice that the websites certificate has been
revoked. I have never had this problem on my old computer (prior to Vista)
and my sister-in-law (whose computer does not have Vista on it) can still
access the same site with no problems. This is very confusing and
frustrating!!!
Can someone please help me???

Thank you for the input. Where do I insert this information in Windows Vista?
