Hi, It really should be able to load this PYD C module! I'm wondering if this is a Python version issue. That has sometimes been problematic on Windows. Sometimes there are issues on Windows with Python 2.6 vs. 2.7 when using numpy together with C modules. I might have to say on the download page (http://www.nmr-relax.com/download.html) that Python 2.7 is required for Windows.
I would recommend either installing Python2.7 (Python2.6 can stay on your system, if you need), or installing the SCons Python module and typing: $ scons in the base relax directory, as described in the 'Compilation' subsection of http://www.nmr-relax.com/download.html#Source_code_release. I hope this helps.
