According to a spokeswoman for Mazars attempts to find a buyer for the business proved unsuccessful.
She added: "Administrators are now looking to break up the assets of the company."
The administrator said that the closure was a knock on effect of related company Response Direct Publishing going into administration on 2 February 2010.
