The file I uploaded was 2ndGW in New Guinea.zip. Just unzip it somewhere convenient. There will be 2 files then: 2ndGW in New Guinea.vmdx and German Marines Readme.rtf. Open Vassal. Right click on the Kokoda entry, and choose Add Extension. Work your way to 2ndGW in New Guinea.vmdx and click OK.Vassal will make a Kokoda extension subdirectory and put a copy of 2ndGW in New Guinea.vmdx in it. Now when you open the Kokoda module, it will add the Dog Days extension, and any other active extensions you have installed. I can try to get the extension form APL, later this weekend, if you are still having trouble.
