LTSpice error using LTC3889 Demo Board


I am trying to run the schematic for the LTC3889 regulator demo board DC2595A on LTSpice, but every time I attempt to run it, I get the following error:

I downloaded the schematic file directly from the LTC3889 Analog Devices webpage.

Does anyone know how I can get around this and/or why this error is coming up?
