Conflict with Media button

I have the Finch WordPress theme installed; it came with Contact form 7. Recently I have developed a strange problem. Whenever the contact form is active, if I use the Add Media button, none of my media files show up in my media library. If I turn Contact Form 7 off, then it works fine. Any help with this appreciated. Site is http://www.feenstraoutdoors.com
