I am trying to add my Gmail email account to Windows Live Mail but I keep getting an error.  I've enabled the IMAP in my Gmail acct by the way.  The error It states, "The server has rejected your login. Please verify that your user name and password are correct."  I have verified that my user name and password are both correct.  Under the error details it lists the error code of 800cccd1.  Which I was able to look up and I think it means, Invalid certificate content.  How can this be fixed and what can I do?
