Phising turned off

I have Norton 2009 Internet security on my computer with 2 different user accounts...phising protection worked on both user accounts until last week. On the administrator account, it still works..(says it is turned on).on the other user account.. I get an error message saying it is off and I can not turn it back on..this just started out of the blue. Is it on or off?? If it is on on the admin account does it cover all users on the computer?

Why out of the blue did I get an error message that it is off and it will not let me turn it back on?
