All im trying to do is select my contact card in Contacts and "Make This My Card" so I can be reminded of appointments through the Calendar.

I keep trying to select the card and the "Make This My Card" and it won't take.

I have tried to delete the card and re-enter; I have tried deleting ALL the records and starting over (I exported by files as a safety, of course) -- nothing.

Good work. :)
