LTSpice issue in using third party model file, throws "Ignoring empty pin current" and simulation is very slow


I'm using a third party model file (from TI) for a buck converter. The model file is an unencrypted file, however when I'm using it in the simulation it says "Ignoring empty pin current" and the simulation doesn't converge. Can anyone please explain why do we get such warning message saying "Ignoring empty pin current" and how can we speed up the simulation and make it converge?

Thanks in advance!
