SSE NifScope Problems?

[ForcefulMocha]

I have meshes from Oldrim that an author put up as a modders resource and I'm trying to put them into the creation kit in a test esp to see if they are working.

 

But everytime I try to I get errors. I've tried using SSE Nif Optimizer on them and it did nothing. It says in the txt document for each nif " [ERROR] Failed to load 'C:\Users\TurboDumby\Desktop\New Folder (2)\boots.nif'. "

 

I tried to do the thing where you make it a .obj file then import it and save it like that and it does nothing.

 

Let me point out that I'm able to see it in NifScope if I do the obj way, but when I try to save it I get the error " block 6 Tangents array size mismatch block 6 Bitangents array size mismatch "

I don't know much about modeling so I don't know what is wrong.

 

If I try to open the mesh directly it says " failed to load block number 6 (NiTriShapeData) previous block was NiSourceTexture Failed to load C:/Users/TurboDumby/Desktop/boots.nif "

 

And If I try to put any form of the nif file into the creation kit as the mesh used for a piece of armor I get the giant red exclamation point and a warning that pops up saying " (BSStream Error) NIF BSversion is too old in meshes\armor\Forceful\boots.nif. "

 

Does anyone know what is going on and how I fix it? I can upload the files if necessary
