PO_GLOBAL is no longer in Version: 4.2.2

Hey guys just updated to Version: 4.2.2 but i see that the pop over is no longer site wide i looked for the code below but it is no longer in popover.php

https://premium.wpmudev.org/project/the-pop-over-plugin/installation/
"For site-wide control, leave as is. For blog by blog control - comment out the PO_GLOBAL line at the top of the plugin file."

I also see the err below

[26-Mar-2012 06:22:19 UTC] PHP Fatal error: Call to undefined function add_action() in /home/blogline/public_html/wp-content/plugins/popover/popoverincludes/includes/functions.php on line 4

Please guys get this fix as i am making money with the popover

Thx
Mark
