HYSPLIT for Mac OS X • Concentration model non-existent LANDUSE.ASC

Hello, I am new to HYSPLIT and I'm encountering an error while running HYSPLIT version 5.3.0 (unregistered) on my macOS 14.5 system. I am running tutorial 2.3 Test Air Concentration Calculation. The model starts but then fails with the following error message:

Model started ...

It appears to be an issue with accessing the file LANDUSE.ASC in the /bdyfiles directory. The error message indicates a "severe (36): attempt to access non-existent record." The LANDUSE.ASC file is in my bdyfiles directory and is not corrupt (i can open it in a .txt file and see a bunch of numbers in a grid like pattern). Also the trajectory test works.

Has anyone encountered this issue before or have suggestions on how to resolve it? Any help would be appreciated!
