MNS Messenger — вообще не подключается! (остальное работает)

Я не могу понять, почему не удаётся подключиться к MSN Messenger. Я смотрел форум, но не нашёл там решения своей проблемы. Если логин и пароль верны, то мессенджер сообщает об ошибке аутентификации, а если они правильные — просто не подключается. Вот правила брандмауэра…
