Fatal error: Cannot redeclare wdcab_add_to_admin_bar()

Hi, I enabled this plugin and am now getting the following error:

Fatal error: Cannot redeclare wdcab_add_to_admin_bar() (previously declared in /home/grnwire/public_html/wp-content/plugins/custom-admin-bar/custom-admin-bar.php:66) in /home/grnwire/public_html/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/custom-admin-bar.php on line 65

Any suggestions? Thanks!
