Oops... yeah, there is a minor problem. When I set up my own version, the textures name was Hussar_Light_Green4.dds, but for the finalized version the textures name is simply hussar.dds. As according to what I read the hussar.nif is not teamcoloured anyways, you can use the hussar.nif from the maindirectory. To fix the _fx.nif, you would have to open the nif with nifskope. There, select the untextured parts - in the tree on the left a NiTriShape will be selected. It has a child called NiTexturingProperty, which again has at least one child called NiSourceTexture. There, you'll find the textures name specified. Correct it (actually it makes no difference if you enter the teamcoloured or the normal coloured textures name here, but I recommend the former as the latter then becomes obsolete and you could delete it, I think) and save the file. In case of the saber, there are two SourceTexture nodes. One is the texture itself, the other one controls the gloss effect. Leave the one saying something about gloss as is. If you haven't worked with nifskope so far, this might sound complicated, but it's pretty straight forward.
I will prepare a new fixed version soon. So if you prefer, you can wait till then.
