Try upgrading to Numpy 1.8 (Available from 
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy -- I don't know why the Numpy 
site doesn't have binaries for Python 3.3). If this fixes the error, please let 
me know and I'll update the installation instructions to indicate the version 
requirement.

Upgrading to NumPy 1.8.1 (RC1) solved the problem. Thank you!
