I'm downloading a model for an n-channel MOSFET, the DMG6968U-7. This is the SPICE code:

I cannot open the file with LTspice (if I try opening it from within LTspice, it does absolutely nothing; if I drag-n-drop the file into the LTspice workspace, it gives me an "Encountered an Improper Argument" error). Please help!
Actually, the above is not exactly the downloaded code — all of the .model
directives were missing the closing bracket (parenthesis), so I added them, but I'm still getting the same error.
