HI - You LM3478 symbol pinout was wrong - you've got pins 5 - 8 flipped...

Its a slow deck for sure - I'll have a play with in in the next couple of 
days.

Also attached slightly reformatted schematic to compensate for change in 
the ASY file.

Annoying that the PSPICE model from TI has a different pin order to the IC 
itself...

Nick
