Not sure what the problem could be. It’s possible that sending the file via email “sanitized” some non-standard characters (particularly end-of-line characters) and therefore the file I received worked when the original file didn’t. Therefore I an sending the file back to you as an attachment. See if it works. I am also attaching a Chimera session with the file already opened so you can at least also get some work done with it.

In a terminal window, what output do you get from the “locale” command?
