The Claw is up to get down(loaded)

[Nikola Pizurica]

OK, I've downloaded it, but how to start it?
I've tried with "python claw2.py" and got this:
--------------------------------------
[root at nikola Claw2]# python claw2.py
Traceback (most recent call last):
  File "claw2.py", line 1874, in ?
    mainApp = Claw()
  File "claw2.py", line 61, in __init__
    self.readPreferencesFile()
  File "claw2.py", line 115, in readPreferencesFile
    prefList.append(prefNode[0].childNodes[0].data)
IndexError: list index out of range
-------------------------------------------
