Fatal Error: Class 'Jetpack' not found

I seem to be having a hard time getting my mp3’s to work on my page.

This is what I keep getting:
Fatal error: Class ‘Jetpack’ not found in /home2/miracle/public_html/sowingfortheharvest.com/wp-content/plugins/jetpack-easy-playlists/jetpack_easy_playlists.php on line 123

That file is in that folder and I’ve tried to follow all the steps correctly.
Any thoughts as to what I’m doing wrong?
Thank you.

UPDATE:

Ok I figured out that I need to install “Jetpack” as well to use this plugin.

Now it displays this message:

Whoops, your playlist won’t work without Jetpack’s shortcode functionality!

Any thoughts?
