Fatal Error with Ultimate Branding Plugin

I downloaded and installed the “Ultimate Branding” plugin and when I Network Activate it, I get this error message:

Fatal error: Cannot redeclare rmw_register() (previously declared in /home/renzomes/public_html/www.abc-hub.com.au/wp-content/plugins/rebranded-meta-widget/rebranded-meta-widget.php:51) in /home/renzomes/public_html/www.abc-hub.com.au/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/rebranded-meta-widget.php on line 45

So I’ve deleted it through the file manager (as the front and back end of my site went down and I couldn’t access anything!). Help?
