Do you mean you are getting partial textures, or that you are getting morphs (new shapes) but no textures at all? Some character makers give separate mat files for the head and body (I think so that you can choose different makeup or tattoo options without loading the unwanted default head or body textures): could that be the case? If for some reason you aren't showing textures (check the setting for display style, the triangle button in the viewport's title bar, to see if it's set to something other than Texture shaded) you will see only the diffuse colour: when the figure is loaded that's set to give a slightly real effect, but when a texture is applied it's usually set to white so that it doesn't tint the texture. Dose a render (cmd/ctrl-r) bring the textures up? If so, and if the display mode is set right, that may indicate a video card or memory problem.
