Installing Membership Premium

Hi there – my client just purchased the Membership Premium plugin, after I’ve already installed the Membership Lite plugin. I tried upgrading by replacing the plugin with the new version provided to him, but I continue to get a fatal error when I try to activate: Fatal error: Call to undefined function load_all_membership_addons() in /home/yaki0795/public_html/missioninstitute.org/wp-content/plugins/membership/membershippremium.php on line 89

Please help!
