Media Issues

I’m using the latest version of the responsive Classified Theme and have run into an issue with Media. I can load pictures to the Media Library, but when attempting to use them with Classified ads or as pictures in my sidebars, the system hangs or does not show the picture in the Classifieds created. When in the Classified creation page, the image buttons do not work, nor do the featured picture links and insert into post buttons. I have disabled all plug-ins and refreshed without success. My guess is that one or more of the files in the Theme is corrupt and need replacement. Thanks
