I couldn't get this map to work in Linux, so I dug around, and found many path references specific to Windows (e.g. "C:\Program Files (x86)\Amnesia...", etc) as well as file references with mismatched case. I corrected as many of the references as I could (all the XML files), but some files were binary, so I can't correct them.
EDIT: replacing paths in the files didn't seem to work, so I just created lower-case symbolic links to the actual files. ZIP doesn't handle them correctly, so I uploaded it as a tarball.
The fixed version is at

here.
