Fix qeq/reax parameter file could not be found

Thank you Ray and Ευάγγελος. I was not included param.qeq in my current directory. After doing this it solves the problem. But I am getting another problem and the error is:

ERROR on proc 0: Neighbor list overflow, boost neigh_modify one (…/npair_half_bin_newtoff_ghost.cpp:157)
Last command: run 3000

Could you give me some suggestions?
