I created a new texture for Ebony Armor and wanted to create a new armor set with it, but when I try to upload my files (which are saved in the proper directories) it says "MODELS: Could not find model (name)"

I have no clue what to do, and many tutorials have not worked for me. can someone help? any help with this is greatly appreciated.

I have applied my textures to the proper meshes in Nifskope and they apply nicely, but actually getting the nifs and textures into the Creation Kit is my issue.

At what point are you getting that message?

If all you want to do is change the texture there's a much simpler method using http://afkmods.iguanadons.net/index.php?/topic/3895-skyrim-texture-sets/.
