Reinstall the Python.

I have reinstalled Python and it still doesn't work

Are you sure that your installer is for exactly same version of Python (32 / 64 bit, version number)?
What is installer file for Python and the installer for the module? If the module is pure Python module installer from source is simple. Normally there is file setup.py and you just issue command \path\to\python\python.exe setup.py install in source directory location.
