Electronic – LTSpice: “Can’t expand empty subcircuit” error with HC4046 Model

I downloaded the symbol and model for the HC4046 Phase-Locked Loop chip from the Yahoo LTSpice group here:

https://groups.yahoo.com/neo/groups/LTspice/files/%20Lib/CD4046/Others%20CD4046/

(You will need an account and to be signed in to view this page).

The one I downloaded and installed was Full_feature_without_inhib.zip. I placed the HC4046.asy file in the default LTSpice sym folder, I put the HC4046.sub file in the sub folder, and put the HC4046.asc file (the subcircuit representing the HC4046) in the same directory as my project. In my project I added .include statements to include HC4046.sub as well as HC4046.asc. However, when I press the simulate button I get an error, Can't expand empty subcircuit: HC4046. I have scoured the net and have been unable to find even a mention of this error much less its cause or how to fix it. In what cases is this error produced, and is there a documented solution for it?
