Fatal error using Texas Instruments SN74HC14 inverter

[Nano81]

Hi guys. I am attempting to simulate a Schmitt-Trigger using the SN74HC14 inverter chip. It is a boast converter, changing 6V to 60+ volts. Here is basic schematic.

Here is a screenshot of my error message.

Here is the link to the Texas Instruments spice model and datasheet.

And finally, here is the .qsch file.

I am assuming the problem is in the model. Any help would be appreciated, thanks guys.

There are few cascades in your circuit to produce 60 V.
