Hollywood,
Never ran into this problem but I'll give it a try. The usual solution for this type of problem is to uncheck the plugins to see if another plugin is causing a problem, all except the appointments. Tell Hal you'll talk with him tomorrow and Hal should say he's making a reminder. You can also manualy put a reminder in the appointment book and see if Hal will read it to you at startup.
The Appointments is a seperate uhp file so I shouldn't think it's a problem as long as it's checked.
