Doesn't work with Chrome?

Hello,
I tried to get a free certificate from here:
http://www.instantssl.com/ssl-certificate-products/free-email-certificate.html

But with Chrome, when I click on “Install certificate” from the email, I get an error 207 (ERR_CERT_INVALID).
Is it Chrome or does my newly created certificate is invalid?

It’s Chrome. It doesn’t quite support Certificate Enrollment yet.

Ok, thanks.
Same for Comodo Dragon I suppose?

Is there a way to get the certificate without using the browser?
