Revoking an e-mail certificate

My free e-mail certificate was operational for 1 year from December 2008 until today Friday December 4th. 2009. I downloaded a new certificate yesterday December 3 but couldn’t get it to install properly. How and where do I revoke my free e-mail certificate and start from scratch to get and install a new certificate ? ???

Hi brucea,

Can you describe the error you had while installation of the new certificate, please?

You can send e-mail to cse-support@comodo.com from the same e-mail address as your certificate issued for and ask to revoke your certificate.

Regards, Eugene.
