LM5145: Can't Use the PSpice model with Cadence Pspice. PSpice for TI is down. Pspice model with LTSpice doesn't work.

So,
I am trying to build a DC to DC Power Supply using the LM5145 and after designing the circuit I wanted to test it out in a Simulation.

The PSpice model does not work with LTSpice, my prefered simulation tool. PSpice model doesn't work in the original PSpice by Cadence. PSpice for TI is down, but I am pretty sure, it won't work there as well. 

So, what are my options?
