msn messenger

Suddenly COMODO began to block msn. In that moment I created a rule to allow msn connection but COMODO continues blocking messenger. What can I do??? ???
Thank you in advanced

Welcome to the forum, spiderstone.

Have you restarted msn msgr yet? Sometimes even a reboot is necessary. But before you do that, check Application Monitor and Component Monitor to see if anything related to msn is blocked and delete / unblock them.
