LTspice error reading a downloaded model
How did you add the model file to the schema? Maybe you have not added the model correctly or have you selected the option?

You must add the model to the scheme as SPICE Directive.Add a n-channel MOSFET symbol and right click on the MOSFET with the Ctrl key pressed simultaneously. In the new window, you need to change the prefix, for example, to “X”, and Value to the value from the model. The model name can be found after the .SUBCKT directive.

You can find more details on my blog:
