How do I revert back to last version. Update is messing up my site

Hello, How do I revert to the last version of Catch Box Free? This update is messing up my site. First, the new Menu icon is appearing just under my navigation bar on the left in regular screen mode - ie. my laptop - which encourages people to click it - which I don't want. WORSE, when I click it, it forces my screen to the left on my laptop and displays a vertical menu at the bottom of every page. When I view it on mobile, same thing. Shifts page to the left and menu is at the bottom of the page. Witness: http://myinfohero.com Plz tell me how to revert back to previous version that was perfect. Thanks, Dave
