As I suspected, your molecules are simply out of order.  Your topology specifies 
EMI-EMI-ETS-ETS, but the coordinate file lists the molecules as EMI-ETS-EMI-ETS, 
hence the mismatch.  The "Protein" [moleculetype] seems superfluous, but would 
be the appropriate solution for this case since it specifies EMI-ETS-EMI-ETS all 
in one [moleculetype] definition.
