Main Sidebar Widgets

Hello, I am trying to add text widgets to my main sidebar, but the theme is not allowing anymore than what I have already added. Is there a limit to number of widgets for the main sidebar in the free Catchbox theme? Or is there somewhere I need to increase the size of a widget box? The things I tried showed up in what looked like the footer. This is the website: http://www.cranburypubliclibrary.org/ The current layout shown on our website is all it will let me add to the sidebar. Thanks!
