[Guide] Ripping models from Sketchfab

Hi, I have a problem with this model
https://sketchfab.com/3d-models/bmw-x5-g...186853560b

Traceback (most recent call last):
File "starter.py", line 1767, in openFile
parser=Parser()
File "starter.py", line 1760, in Parser
osgParser(filename)
File "starter.py", line 1723, in osgParser

File "C:\Blender 2.49\.blender\scripts\newGameLib\myLibraries\meshLib.py", line 822, in indicesToTriangleStrips
f1 = indicesList[id]
IndexError: list index out of range

I saw a similar problem a couple of posts ago, but I didn't find a solution. What I should do to make it work?
Thanks.
