If you followed the directions then it had to work. No one else has had any problems with the directions I've given.

If it turned all black in Lithunwrap, that is either because the normals are all facing the wrong direction or because the texture you created for it is all black. Or because the material specifies black as the ambient, diffuse and specular color for the material.
