Rounded corners gone

Hi!

I've updated to the newest version of Atahualpa, and got some problems. First I had nice rounded corners that are now gone, the code in CSS Inserts seems to be there though ... Also I had a light box effect done for me, bringing up each individual image on my site as a "pop-up". Its also gone, and the guy who helped me making it can't seem to figure out how to restore it ... any input that could help him/me is very appreciated!
