Hi Rudl, have you been able to contact the author of the script? I think their e-mail address is listed on the page there - they would definitely know the most about it...

Since it is a Rhino script, you also might try asking on the Rhino newsgroup here

Let me know if none of the above helps any and I can try to take a look, but it will have to wait until after I return from vacation next week.
