I guess you mean 4.14.1...if you really do mean 4.4.1 then that's a 2005 version & that won't work with Vista. Double check to find out which version you have.

Just double check that the Windows firewall is off if you're using Norton. The 2 firewalls will conflict with each other if they're both on.

Please can you give us your system details???
