Edu-Clean and NextGen Gallery Widget

I'm running Wordpress 3.0.1 multisite and am using the edu-clean theme...I'm trying to get the NextGen Gallery Widget to work on the right home sidebar, but it won't show my image thumbnails no matter what I try. NextGen Gallery is working fine (you can see a gallery page of themes in to nav bar)...but the widget isn't working. - the NextGen Slideshow widget works - so...I'm stumped. Anyone?

and it's seriously underconstruction, so forgive the funk. :slight_smile:
