Kontera and WordPress?

My blog: http://www.nickkoesling.com — I have tried to put Kontera link ads on my blog. The problem is I dont know what file to put the code in. I figured the best place to put it would be in my theme’s footer.php file. But the ads wont show up. So i’m really confused as to where I should put the code they gave me.
