[pygame] error code 193 on pygame import

[ellerymsg]

Hi, I am very new at pygame/python (I just started today) and am
following this tutorial: http://rene.f0o.com/mywiki/LectureThree which
tells me to do
>>> import pygame, sys,os
but when I do so, I get:
>>> import pygame, sys,os

Traceback (most recent call last):
  File "<pyshell#14>", line 1, in <module>
    import pygame, sys,os
  File "C:\Python25\lib\site-packages\pygame\__init__.py", line 95, in
<module>
    from pygame.base import *
ImportError: DLL load failed with error code 193

Can anyone help me?

Thank you in advance
