How to use DLVO potential in LIGGGHTS?

I have successfully compiled the colloid package from LAMMPS in LIGGGHTS, but I encountered some problems when I use it.

The error message:
ERROR on proc 0: Overlapping large/large in pair colloid (../pair_colloid.cpp:187)
ERROR on proc 4: Overlapping large/large in pair colloid (../pair_colloid.cpp:187)

Thanks.
