Problem with Unity FBX import from Moho

[GHOSTYMPA]

I have been trying to use the FBX export from Moho to put animations into Unity, but whenever I import anything, it has an error for every sprite saying "Mesh [sprite name] has no normals. Recalculating normals." and I am not sure why this is. I have put the FBX importer script provided by moho in my unity project. Any help would be greatly appreciated!!
