Hi, Just installed
Please note that I had to manually upload the language file from admin, as the folder structure seemed to be incorrect when uploading, but manual upload got it working fine - you may want to fix in future releases.

Zen structure is : admin->includes-->languages-->english-->extra definitiions

Module Structure is admin-->includes-->english-->extra definitions


That might be why some folks are having problems with uploading and seeing the configuation menu in the admin end. :)
