sooooooo
new try, now with "show texture" box checkek ;p
So i imported your fbx : normals were weird > unlock normals > smooth all. I also tried to clean uvs so that you'll use less vertices with a similar render (few littles seams noticable from close). Then baked a quick hipoly and here it is : no issues.
So seing your fbx, i think you did not smooth correctly your vertex normals :
