Unable to export to nif. files in Blender

Making my first body mod for Oblivion

I have the PyNifly plugin, as well as the Niftools addon, yet when I try to export my file as nif. , I am greeted with the error message at the bottom of this page. I am working on my first body mod for Oblivion, trying to edit/import/export models and such. 

Python: Traceback (most recent call last):

Have you tried to import a vanilla mesh and then export it without making any changes? Those errors look like something major not related to any work you may have done.

Where I see "Blender\4.0" does that mean you have installed Blender 4.0? I'm a noob myself but I don't think modern versions of blender will export to Oblivion. You might be able to do model work with newer versions but then have to use 2.49 to do the export. I've used This and there is also a portable version on the Nexus that works as well.
