Model Help?

[NaisBully]

I wanted to make some custom characters through blender, but it didn't work.
I downloaded script 2.58 and blender 2.58 so they'd match. Then I extracted the zip to; C:\Program Files (x86)\Blender Foundation\Blender\2.58\scripts
When I loaded Blender, it hadn't made any changes at all. When I tried clicking open with recommended programs on the actual file, it loaded and a cube was there, like normal.
I then tried switching to Nifskope. In Nifskope, I made a miniuture Mandy, which is in screenshots below. When I saved the file then added it to game, Mandy stayed her normal height. What am I doing wrong on both accounts? About the blender thing I saw this thread; http://bully-board.com/index.php?topic=13766.0
Sorry for the paragraph and thanks in advance!

I will look at this in more detail for you and see what I can do to help.

I myself use 3d studio max rather then blender since its my preferred choice for 3d model editing.....so my knowledge regarding blender is rather limited, but I will see what I can figure out for ya
