Friends add me cannot login!

Today, I was told friends add me as MSN contact freeze their MSN. And they
cannot login again!

I registered a new passport and tried to add my passport in Windows live
messager. The messager freezed and cannot login using the new passport again.
But other passport can login.

Also, I found that the new passport also can make other passport cannot
login if they add it as a contact.

Please help to check what's wrong with these passport: my gmail passport
currently using and a test passport .

For the , I can provide the password if needed.

Thanks.

You can try to add as a contact. But maybe you
CANNOT login again.
