I am have a problem with security certificates on many of the web pages I visit. I am getting a messege that states “There is a problem with this website’s security certificate. Certificate presented has expired or is not yet valid.” I have checked and/or changed many setting on my comp. to see if I could resolve the problem to no avail. I have checked the certificates in question and they are in fact not expired and are valid. I have even tried installing the certificate which makes no difference. I am running windows xp home edition and IE7 for my browser this problem seemed to begin after my router went down and I had to connect to the internet directly through my modem. Can anybody help me resolve this problem any suggestions would be greatly appreciated. please keep in mind though that I am not an expert but more of I’d say between a beginer and a novice
