Squawkbox multiplayer trouble

I am hoping someone can help me as I am not able to figure out whats wrong with my conection to squawkbox with fs9. I have windows xp64 newly installed and I am trying to get back on line with squawkbox. I have installed SB3 and I have tried SB4 also but they both run into the same trouble as I end up with a message saying unable to initiate a multiplayer connection and squawkbox closes. I have rau the dxdiag test as instructed by SB and it shows all conections are working okay and routing correctly but SB will not connect to a multiplayer. I have tried manualy setting the IP address in fs9 multiplayer but thet does not detect any sessions to join either and I now do not know what I need to do. The squawkbox web site has no links to a solution to this problem....please help with step by step instructions if I need to alter the setting in the computer
