WLM message name@aol.com is not in your contact list

I'm kind of new to this messaging. I had the impression I could do
this but ....

I set up WLM v8 on my XP workstation. I added a contact with their
aolscreenname@xxxxxxxx If I double click on this person's icon it
opens a messaging window and in the row just below the icons of this
window there is a message that says aolscreenname@xxxxxxx is not in
your contact list. CLICK HERE TO ADD HIM. When I click on this link I
cannot tell that anything actually happens. Afterward - I still get
this message when I open a messaging window.

I would appreciate any help.

Thanks.
