I am going to take a wild guess at this one. My sister had the same trouble awhile back, it was because our system was blocking her email as spam.
As far as fixing it, I don't have a clue, because im NOT an IT guy and this computer stuff is way beyond me.
Also John I will go out on a limb here and give you another email for you to try. If you use the new email, expect a wait time because its all new to me and I don't chck it regularly.
