WordPress 3.2.1 made my slider images disappear

Hi, I just updated to 3.2.1 and I updated the Studio Box theme to 1.4. The only problem is that my accordion slider images on the home page have disappeared. They come up as a big black box. I’ve contacted the Web host and the theme author but so far have not been able to resolve the problem. Is there something with 3.2.1 that I need to adapt that could fix this? I did unplug my plugins before updating, just FYI. The site is http://www.greatriverpassage.org Thanks in advance for your help.
