I have hal,dbus & fam in my DAEMONS and I have added myself to the optical and storage groups.  I have also logged off and on and tried restarting, but I still get this error.

I'm using the gnome desktop.

This same question was asked on the forum in October of 2006 but with no response. Can anyone please help.
