In order to use the Listen Player to answer the listening portion of the quizzes, you will need to install the free CD Pro plugin. Please choose the correct installer for your computer system. Save the installer to your computer, expand the file (.zip file for Windows, .bin or .sit file for Macintosh), and then launch the uncompressed installation file.

You must have Shockwave 8 or later BEFORE running the CD Pro installer.

If you don't have a program to expand compressed files, download the free StuffIt Expander for Windows or Macintosh to uncompress these files.
