I have had this problem before and it has returned even tho i changed my email address..

When I add a new contact to my contact list, or they add me, my msn fails to show they're online -

they can talk to me and my msn says "xxx@hotmail.co.uk is not in your contact list. Add this person to your contact list"

Of course, the option of clicking "Add ths person to your contact list" is there, but when i click it, nothing happens and msn does not add the contact to my contact list

although it allows me to reply to them once they've initialy tlkd to me, i simply can't tell whether or not they're online and this is the same for every new contact..none of them add properly ( i can't see when they're online)

Any ideas ?
