hello Im using a MAC, trying to unzip the new 1.5 update. when it unzips using archive utility it turns a ZIP file to "CPGZ".?? I have tried 4 times and it remains this weird format that my phantom will not recognize. Now I got a bunch of zip files on my desktop. I dont get the usual folder with 2 files, a PDF file and the update. I downloaded the older version and it unzipped fine but it doesnt seem to like the latest one. I am not about to purchase WINRAR . please help
