"Fatal error" My page doesnt load and shows an error page

My website wipecity.com doesnt load and shows an error page after I downloaded the braintree paypal plugin for woocommerce. I didnt use woocommerce for a long time, activated it to test it with the braintree plugin, and then i tried to deactivated woocommerce, and this is when the error page popped up and my page doesnt load after this incident.
