I have tried on several occasions to change my son's email address, and to add contacts to my contacts list in various ways but each time I get a message telling me :- "The contact information could not be saved. Check the contact's information and try again."  This of course I have done to no avail, and the irony of it is that when I close the window it asks me if I want to save it, and then won't let me!  It's as if Windows has now blocked me from adding contacts to my list.
