Category list in page stopped working

All the category lists that made up the pages under "Musician Roster" in the menu at http://www.creativemusicphotography.com have stopped working. One such page is http://75.103.101.29/wp2/?page_id=11251 and the code on that page - [catlist name=comp_jazz,duets numberposts=-1 orderby=title order=asc] no longer displays the list of posts. Any help would be greatly appreciated.
