issue importing certificates or adding certs to sites

[kdovale]

when you install a certificate on a site it comes back and says that it detected an installed certificate, not like the other servers where it shows you the newly installed cerificate settings, if you try import the certificate it errors out with the following

System.NotSupportedException: The certificate key algorithm is not supported.

Im not sure why this server is moaning like this, im busy testing this issue on other servers to see if its specific to this server. I have checked the certificate stor, made sure no certs exist, i also checked the wacs dir and removed the certs, but same issue.
