Error while loading DyalogTutor_EN workspace in Dyalog APL, how to proceed?

Question

I am unable to load the DyalogTutor_EN.dws file in Dyalog APL for Mac. The error is "There was an error ("TRANSLATION ERROR") with the specified file". How do I load this file in order to follow the book Mastering Dyalog APL which uses examples from this workspace?
