I haven't re-read the readme file for that addon in quite awhile.

However, here's what you do:

1. Unzip the zip file to your PC. Make sure it expands the many folders included in the zip, so that you have files inside several layers of folders.
2. Use your FTP program and delete the zip file you uploaded earlier, and its readme.txt file.
3. Use your FTP program to upload the unzipped folders/files from your PC into the matching folders on your server.

Then your menu option should appear.
