(Shadowbox Plugin) Help Would Be Appreciated

Hello, I’ve been trying to figure out this certain problem for a few weeks now. The Shadowbox Plugin doesn’t seem to work on my blog. I have this website – http://alfatir.com/blog/videos – And you will see 2 links in the post area, the top link opens the shadowbox but the video never starts to play, no matter what video it is, and if you click the link under it, it will just take you to vimeo. I wanted to know if someone knew how to fix this to make the video start to play. I’ve been on a few forums, but my question just seems to get ignored or no one knows the answer. If you can help, please do. It would be much appreciated, Thank You.

The Plugin I’m Using Is – http://ww.wp.xz.cn/extend/plugins/shadowbox-js/
