Installed Windows 7 Service Pack 1 yesterday. Today, Windows Live Mail is asking for my username and password for my Comcast mail account. The name & password provided are correct. When I OK, the box just keeps reappearing. When I cancel, error message states a wrong password was provided. I am using Firefox as my browser. When I try to open my Comcast mail from the Comcast site, it times out. I AM able to send emails from Live Mail....any ideas?
