I messed around with this script for like 40 mins and couldnt get it to work. Which is a shame. Cause i would like to have it work myself. I tried maya 5 and 6 and still no luck. There is no help file with this script, and seems to be very poor in the way of instruction.. hmm .. like NONE at all. sorry couldnt be more help to ya.. Maybe you could email them.
