Checkout not working in Internet Explorer

I’m using Jigoshop 1.12.2 with a SSL page for checkout. Checkout works just fine in all browsers except Internet Explorer. When I click proceed to Checkout, the page loads and I receive a message from IE that says Only Secure Content is displayed. No matter if I choose to show all content or not, a wheel turns on the page and the order part of the page is grayed out and unavailable with a wheel turning over that section. The Billing and Shipping area is accessible and I can enter the info. However when I click place order the page completely grays out, the wheel continues to spin and nothing happens. I thought maybe it was the ssl so I removed force SSl checkout, cleared the history, tried it again and it still didn’t work. Site link – http://www.susansleeman.com/shop/
