as many people have already stated when you attempt to host your set the error message that comes up is as follows " error #4 ;
Port 42480 is closed, attempting to find UPNP devices"
upon clicking the only button on the box you are met with a message saying "binding failed" which then closes the window. this is a really irritating issue and ive asked everyone i know and no one has any info on it. PLEASE HELP if you are having the same issue please reply to this thread so that we can all get what were looking for and actually be viable. THANKS
