Well, looking at the texture, your UV’s are all fouled up. It looks like planar mapping, with some stray polys. You’re going to need to remap the model.
ok guys unwarped it again: my uv map in 3ds max(rules!!):
.giant circle on the mouth!!!1.wtf guys wery need help!!! please icant create any content with that lag!!! help!!! 
The problem is still in your UV’s from what I can see. Are there any over lapping polygons?
tool>texture>uvCheck.
If anything comes out red then you have over lapping and Zbrush can’t calculate textures with that.
my uv map is red!!! …please teel me what to do i using deep uv…to unwrap!!!
how are you importing your UV’s?
what does your Unwrap look like?
