Question : IIS 6.0 certificate wizard is not installing my certificate

When I try to install my newest certificate, as my current one is about to run out, the one I have been sent by my companies ISP, I receive the following error:
"The pending certificate request for this response file was not found. This request may be cancelled. You cannot install selected response certificate using this Wizard"

I don't get why it wont install. I am using the wizard in IIS 6.0 to install the certificate. Also when I double click on the new .cer file, usually it will bring up the properties of the file, but when I double click on my new one I get a text box titled: Invalid Public Key Security Object File. Then the information message in the box reads: This file is invalid for use as the following: Security Certificate.

Why is my new certificate not being picked up as a recognized .cer file?

You could try installing the certificate somewhere else, maybe to your personal certificate store through the Certificates mmc console.  This would tell you if it is a valid certificate.  How was the cert sent to you?  You could try re-downloading it.
