OK, I have done as you said and I found an exception trace in the output file. It is repeated several times, but it's always the same one. There it goes:
Traceback (most recent call last):

ImportError: DLL load failed: No se encontró el proceso especificado.
So, somehow the pyexpat module is missing. I tried to install it via easy_install and pip and it didn't find anything for "pyexpat".
Thanks guys!
