if you go to the bottom of this page:
http://forum.beemaster.com/Then in the ventrilo status window,click where it says IP:beemaster.instant.net it should launch ventrilo for you.
Otherwise beemaster.instantvent.net is the server and you need to use port number 8896.
This is assuming you have downloaded the ventrilo program from here:
