PSpice netlist, no ground net problem

I'm having serious problems modelling the infinite resistor grid problem. When creating a PSpice netlist from OrCAD I am being told that I haven't included a ground net. However, I have added plenty of ground symbols (Place->Ground) and have ensured that the net name is "0".

Any ideas about what's going wrong here?

Regards,
Pedro

Apparently an update is out of the question.
I've tried multiple simulation profiles but I always get a netlist generated like the one included below. No matter how or where I add GND symbols, no 0 net appears in the output file.
