I'm losing faith in Microsoft AND my mind. I try to load the program and it goes through the basic check for updates and license info. Then it says downloading . . . then I get the error message. I called for tech service, and the lady from India who spoke very broken English said it would be $139.00 for the fix. As far as I know, there is no other software that is interfering. I ran the Norton cleanup and removal program, but it didn;t help. Does anybody know of a better solution? Thanks, Ed
