Using PMW?

Please pardon my ignorance regarding this question, I'm new to Python.

I'm running Python 2.2.3 (win32) with the latest download of Python
MegaWidgets 1.1. I'm attempting to run the demos but get the following:

C:\Python22\Pmw \demos>python all.py
Traceback (most recent call last):
File "all.py", line 84, in ?
DemoVersion.set PmwVersion()
File "DemoVersion.py ", line 32, in setPmwVersion
if version in Pmw.installedve rsions():
AttributeError: 'module' object has no attribute 'installedversi ons'

C:\Python22\Pmw \demos>python colors.py
Traceback (most recent call last):
File "colors.py" , line 44, in ?
Pmw.initialise( root, fontScheme = 'pmw1')
AttributeError: 'module' object has no attribute 'initialise'

Is this a problem with the libray not being found? I've read the docs with
the widgets and it seems to be straight forward. I'm hoping someone has the
answer.

TIA
