NumTut installation problems

I have been attempting to install the 'NumTut' package on my Windows95
laptop.
I have (I think) the correct installation of Python 1.5.2 and the
Numeric extensions.

I have also seen a series of messages on SourceForge concerning a very
similar problem,
however, I am still stuck. The follwing is a copy of my PythonWin
interactive window:


> >>> from Numeric import *
> >>> from NumTut import *
> Traceback (innermost last):
>   File "", line 1, in ?
>   File "C:\Program Files\Python\NumTut\__init__.py", line 14, in ?

>     return Unpickler(file).load()

>     raise SystemError, \

>  from module Numeric

Can anyone shed some light on what this actually means?!
(This is my first tentative look at Python - not a good start!)

I might add that testview.py and view.py (which come with the NumTut
package) seem to work just  fine.

Many thanks
