MCP6N11 LTspice model not working

The fault may not lie with the amp model itself. It's a common error message. Try adding a few parasitic values to components in your schematic., e.g. give any voltage source or inductor some small but finite internal series resistance.

Try right-clicking V1 and/or V2 and setting its series resistance parameter to 1 Ohm. Adding a decoupling cap of 1uF across V1 and/or V2 might also help.

So it seems the problem could well be within the IC model.
Does putting some small resistance between Vref and Vss make any difference?
You could also try editing the simulation command by checking "Skip initial operating point solution".

Well, for starters R94 and R97 can't be zero. So I will change their values to 0.2 for now, again it's late for me. See you later.

I've just noticed your model seems to be for the 'Minimum Gain = 5' version of the chip, but you have set the gain = 2 via R93,R96. Could that be an issue?
