Pair_style meam/c

Dear lammps experts,
I am going to apply Pair_style meam/c command for simulation of Mg as below:

pair_style meam/c
pair_coeff * * library.meam Mg mg.meam.txt Mg

In pair_coeff commands I inserted below parameters required for simulation of Mg according to this paper(Modelling Simul. Mater. Sci. Eng. 23 (2015) 015004 (19pp)):

re = 3.19
Cmin = 0.49
Cmax = 2.90

However, I got this error as follow:

Reading potential file library.meam with DATE: 2012-06-29
Reading potential file mg.meam.txt with DATE: 2007-06-11
ERROR: MEAM library error 2 (…/pair_meamc.cpp:592)
Last command: pair_coeff * * library.meam Mg mg.meam.txt Mg

any comment is highly appreciated.

I was getting the same error, when I was not using the order of elements as mentioned in the library. But in your case you have only one element.
