Armor I ported won't work ingame, what am I doing wrong?

[halo4life]

I exported it to Nif from blender with the setting 2.whatever.5, which is what a tutorial said was the nif version oblivion uses. When it exported though, Scene Root wasn't at the top, some other thing was. So I removed the thing at the top, and then Scene Root was the NiNode at the top. I had to reselect the texture (though it was set to the proper name) to get it to show. I "updated tangent space" and "made skin partition" to it's (yes, only one) NiTriShape. I saved it over my previous nif. When I loaded the save (with the test mod enabled), and put on the armor, the parts it covers were invisible.

 

Here is a picture of the nif in nifskope:

It's large, so I linked it.
