Recent Prosites Update Killed my Admin area

Well the recent update killed my site, just the admin. Here is the error code from my log:

[19-Mar-2016 05:15:28 UTC] PHP Fatal error: Call to undefined function is_user_logged_in() in /home1/jfrancis/public_html/wp-content/plugins/pro-sites/pro-sites.php on line 1799

    Hello jnkfrancis,

    I hope you're well today and thank you for your question!

    Please try following steps:

    - go to this page (make sure that you're logged in into your WPMU DEV account)

    - click on gray "Download Plugin 3.5.2" link in order to download .zip package with Pro Sites plugin
    - extract (unzip) downloaded file to your local drive
    - access your site via FTP
    - go to "/wp-content/plugins" folder
    - delete the "pro-sites" folder from there
    - upload "pro-sites" folder form an extracted .zip archive on your local drive to the "/wp-content/plugins" folder on your server

    If everything went fine you should now be able to login to your network admin and enable plugin back (all the settings should be maintained).

    I'm suggesting this because I suppose that something may have gone wrong during an update procedure (I tested automatic update on my own multisite test site just a few minutes ago and it seems to be working fine).

    Let me know please if it helped!
    Best regards,

Thank NAME, for their help.
