ImportError: No module named Numeric

I am very new to matplotlib. Trying to start the <a
href="">tutorial, </a> the
very first script, the first line of the script, throws me this error. I
have installed scipy version 0.5.0 for windows, and numpy version 1.0b1

i followed the instructions and made sure to install numy version 1.0b1
first. I have also tried to uninstall scipy and drop back to the latest
0.4.9 version and had no luck. Does anyone know what I can do to fix this

When pylab tries to call numerix\ it is trying to figure out
whether to call numpy, numeric, or numarray. Since it defaults to numeric
I've tried to change the default to numpy, and that returned no luck.

from pylab import *
