Dear Brendan,
  Please email me both your vrpn.cfg file and the .vmdsensors file
and we'll be better able to help you with the problem you're encountering.
It seems that VMD doesn't like something in your .vmdsensors file, but
in order to narrow it down, we'd like to see the whole file.

Thanks,
  John Stone

I've installed VRPN and used the printvals program to ensure that VRPN is communicating properly with the wand, which it is - it prints out both tracker position and orientation as well as recognising all the wand buttons. In the VRPN configuration file vrpn.cfg I simply name the Isense900 - Tracker0 and then modify the .vmdsensors file to be : device fastrak vrpntracker://aelous/Tracker0:0. I then go to the Tracker meu, create a tool, then try to add the device and get the error message:
