Can't see the images, can't purchase the theme

 Hi,
I am a big fan of this theme and absolutely love it, having used the free theme for quite a long time. However, now that I want to download the theme, I can’t see any of the images on this webpage (http://www.designwall.com/wordpress/themes/dw-timeline-pro/). Not only that, every time I try to purchase it, I am told ‘Error: Your cart is empty’. Now, I am starting to doubt whether this theme has been updated and still up for a purchase. Can you please help me with this?
