It's an Artisteer template.
Sorry, but i can only give support for jDownloads.
So you must post your template problem on a general joomla (or Artisteer) forum.
By the way, i have ssen, that on your website exists only the mainbody, nothing columns left or right. I know also, that users here in the forum has sometimes problems with a template from Artisteer.
It exists many houndreds free templates for joomla...
