how to fix the widget for the edu-clean theme?

after installing edu-clean theme, the front page has a side-bar with no widgets.
the message in the sidebar reads: Please log in and add widgets to this column.
and there is a "Add Widgets" link going to the widgets section. No matter how
many widgets I add nothing changes in the main page. widgets for other pages
(e.g. members) work. it is just the home page that doesn't work. I was hoping to
add at least the blog-roll.
