Problem with Site Wide Text Change Plugin

Hi,

It looks like it's impossible for me to activate the Plugin, I get this message error:
Could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare set_swt_url() (previously declared in /wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/site-wide-text-change-files/sitewidetextincludes/classes/functions.php:8) in /wp-content/plugins/site-wide-text-change/sitewidetextincludes/classes/functions.php on line 16

Maybe a compatibility issue with Ultimate Branding plugin?
Appreciate your help!

Thanks
