Sidebar Widgets Don’t Work, Please Help!?

I really hope someone can help… I’ve dug through answers in Support and found nothing that seems to answer my issue.

Anyway, I’m using JD Sky 3c 1.0
http://themes.wordpress.net/columns/3-columns/1773/jd-sky-3c-10/

Which claims to be widget ready, yet nothing changes when I edit the widgets.

Any ideas?

Thanks in advance!
