How do we update the security certificate for web administration? This is the error I am getting in Firefox, a pop up error:

"You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:
Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.


You need to clean out the old RouteFinder certificate that is stored in your Firefox browser or you can create the site certificate in the RouteFinder webadmin under adminstration -->site certificate.
