Eventbooking Error

When I try to load the page http://www.conbrajur.com.br I receive this error:

Fatal error: Cannot redeclare EventbookingBuildRoute() (previously declared in /home2/treinoes/public_html/http://conbrajur.com.br/components/com_eventbooking/router.php:16) in /home2/treinoes/public_html/http://conbrajur.com.br/components/com_eventbooking/router.php on line 358

How can I solve it?

Thanks,

Marco Querini
