Weird MS error. Have not seen it before... I guess the OS is printing
that when you open UDP sockets? I would google around for it. Maybe you
have a firewall or something enabled. A wireshark capture might also be
helpful to show when the socket is barfing (if that is the case).

I never ported the wx gui sink support to the build system. You will
need to use QT. Choose the QT GUI option in the options block for your
flow graph.
