Default Tube Library Pspice error

I've been working on a class AB push-pull amp for a school project and have gotten to the point where my instructor wants me to run some pspice simulations of my design. I searched around for Tube models and found a number of resources to accomplish what I needed.

Rather than making my own models I found some already made library's at:

They show up in Pspice, and have parts that I can place in my schematic, but when I run a simulation I keep getting the following error:

.lib "nom.lib"

*Analysis directives:
.PROBE V(*) I(*) W(*) D(*) NOISE(*)
.INC ".\crapola-SCHEMATIC1.net"

**** INCLUDING crapola-SCHEMATIC1.net ****
* source CRAPOLA
R_R1 N00137 N00107 1k
R_R2 N00166 0 1k
X_VL2 N00137 N00166 0 12AX7
V_V1 N00107 0 200Vdc

**** RESUMING crapola-schematic1-asd.sim.cir ****

ERROR -- Subcircuit 12AX7 used by X_VL2 is undefined

I just used a couple of random resistors and a DC powersupply to generate the error message... those elements are not part of my design.

Any ideas on how I can resolve this?

I've tried to go into model editor and generate a usable library, but that didn't resolve the issue, and from what I can tell the model parameters that are used are comparable to other models from sites like duncan amps, or norman koren.

Thanks in advance for the help.

PSpice can't find the 12AX7 model... it isn't loaded.

What tool are you using?
