Dear Yaser, Gro file is sensitive and you should update the number manually after adding the ligand atoms to the protein.gro file. Check the first line of your protein.gro and ligand.gro. In the complex.gro the first line should be the summation of both. Gromacs does not perform it manually. Kindly chck again and rerun the grompp.
