Okay seeing no one responded I kept trying and finally worked it out. It would seem my problem was related to windows permissions around the executable. I would highly reccomend to anyone that is having problems getting this extension to work to go to the Ventrlio home page and download the PHP Ventrilo Status Scripts
http://www.ventrilo.com/download.php
It contains a very good readme file of how to set it up and some sample scripts that let you trouble shoot.
Once you have this working then you will be able to confidently get this plugin working.
Oh btw, thanks for this great VBulliten extension.
