Sidebars are not displaying widgets

I do not want to buy the pro version if this theme does not work.. It seems that only the “Main Sidebar” layout works. The layout does change, but the widgets do not display in the sidebar area. The sidebar only shows an “Archive” widget (which I believe is by default). I am able to add/display widgets in the footer and home sidebars with no problem. Also, the “Top Widget” sidebar seems flaky, it will let me add a search widget but not a text widget. Is this something that is being worked on? Is there something I can do to fix it in the meantime?
