I am trying to simulate a simple circuit using the opamp LMC662 from Texas Instruments. I imported the file as provided in the product website: www.ti.com/product/LMC662/toolssoftware
However whenever I run any simulation i get the error:
G4: unknown circuit node: "1" requested in behavioral source.
I have no idea what this means and how to solve it. Only thing that I found is that in the model file there are the lines:
G4 98 16 POLY(2) 1 49 2 49 0 3.54E-8 3.54E-8
G4 98 16 POLY(2) 1 49 2 49 0 3.54E-8 3.54E-8
which refer to node 1, which is defined as the non-inverting input of the opamp:
.SUBCKT LMC662/NS 1 2 99 50 28
Im attaching a screenshot of the schematic.
Any help is greatly appreciated!
PS: The ltspice model is here (it's in the zip file).

I managed to solve the problem by using a different library from National Instruments which contained the LMC662/NS. It can be found here. I still have no idea what was wrong with the original one.
