General rule - when you see green texture, it means that texture couldn't be applied on that place. So it has either incorrect (corrupted) BLP file, or that BLP file is simply missing. Check that model in 010 and find list of textures used (just search for .blp) and check if you have all listed textures in you MPQ. If you do, check if those textures are all OK (if they don't have wrong size or something like that). If you lack some of textures noted there, get them. Or create a new (transparent?) custom ones.
