The certificate details that I see for the login.comcast.net domain show 07/27/2010 to 08/13/2012. Are you sure the date / time is set correctly on your PC?

You won't lose your personal data by installing Firefox 6.0.2 over 6.0 - that's the same thing the "update" will do when you're more than one version behind the current version, except that the "update" will download the uncompressed version for automatic installation.

Thank you Edmeister... 1-How do I verify date on the pc? 2-Will downloading 6.0.2 solve the problem? Thank you

Lower-right corner of the screen, double-click on the time display.

Time / date are set correctly. Just installed 6.0.2. Still getting "server license expired message" (also updated to newest flash player).....
