Security warning: ‘The certificate’s CN name does not match the passed value’ on launch

When I try and open Windows Live Mail this is the message I get:

INTERNET SECURITY WARNING

The server you are connected to is using a security certificate that could not be verified.

The certificat's CN name does not match the passed value.

When I press yes, it just carried on spinning and never opens.

HELP PLEASE.
