I recently upgraded to 11.2, running on a mac. The HiveWire content was added easily. The Legacy Content and LeFemme zips won't add via "Install from zip archive (path set to Poser 11 Content)," and if I double-click on a folder a dialog box flashes by faster than a speeding bullet and it creates another folder, a .cpgz file. If I double-click on that, it creates a copy of the first folder. What am I doing wrong?
