I've followed the steps given on http://niftools.sourceforge.net/wiki/Blender, which state to install(in this order) Python 2.6.6, Blender 2.49b, PyFFI 2.1.11, and Blender Nif Scripts 2.5.9 (of which I downloaded the largest and most downloaded).

Now the problem I'm having is that, when I go into Blender "File / Import / NetImmerse/Gamebryo (.nif) / Program Files (x86) / Steam / SteamApps / common / Oblivion / Data / Meshes / weapons" , the only information I find inside is that for my downloaded mods for Oblivion. And not just for weapons - the only information I can find beyond "Data" is for my mods.

What have I not downloaded, or done improperly?
