Module talk:The Hunters: German U-Boats at War, 1939-43

Hello, Firing up The Hunters after a few months away. I find that I am unable to save a game in progress. I get a window that says

Unable to write file.VASSAL was unable to write the file '/Applications/Vassal Mods/The Hunters/test save.vsav'.

When I go to Show details, I get:

Any idea what is happening, or what I need to do to remedy the situation? I am on a Mac running OS 10.8.2. Vassal version is 3.2.15. The Hunters version is 2.1.
