this exception occured when the current port is already in use or the address cannot be assigned,
you can download TCPView applications which show all processes & their ports :
try changing the default port to something like 8282.
That was the first thing I thought aboute to change port but I was afraid that demo pack may depand on default settings. Thx for link to that application. I'll check that as soon as I get back home:)
