Internet Explorer 8.0 SSL Certificate issues

Using Internet Explore 8.0 on Windows 7.0, it seems the Comodo certificates are failing to be verified up to a trusted certification authority… Has anyone seen this? Is this a known issue with Comodo SSL Certificates?

Which sites are failing?

Hi.
We too are having issues as customers try to checkout on our website:

Firefox ok but not IE8

I’m having trouble reaching your site with IE7. I suggest you send in a support ticket with an updated CSR of key bit length of 2048 and we’ll re-issue your certificate. This should solve your problem.

Ok, thanks for the quick reply

Cheers!!
