Error message when importing a mesh

I've tried to pick up meshing again and did exactly as the tutorial I'm watch said but I keep getting and error message and I don't know how to resolve it. I've tried deleting and reinstalling the latest update for mac but it still keeps giving the same message:

Does anyone know what this means and how to fix it?
