Okay, I just installed the Python interpreter and library. Blender recognizes the install, and the error is gone. However, my .3ds files still do not contain any mesh data. It is absolutely the weirdest thing.

In regard to D.R.'s question, I can export to Indigo using Indigo Export 1.21. www2.indigorenderer.com/joomla/forum/viewtopic.php
However, that only contains the render information. The .3ds file is still needed.

It is better to do one thing well, than to do many things and excel at nothing.
