Hello,After using FlightSimulator for a number of years I thought I would finally take the plunge and fly with Vatsim.....I've downloaded everything required,installed to the letter,and all I get when I run Squawkbox is "SB has encountered an error and needs to close".Any help would be gratefully appreciated as I really want to give this online flying a chance.Thanks,Regards,Martin.Ps. I've read the thread below and that solution doesn't work for me.

Do you have a router? Have you opened the ports needed?Do you have the WinXp firewall running? That will cause this problem.Do you have Norton/McAfee running? Both of these programs will cause this problem.
