IMPLAN Article

Hello, I am searching for an article "Estimating the Contribution of a Current Industry Using IMPLAN Version 3.0" by Alward, A. 1999. There is a link given in for the article as "www.implan.com/V4/index.php?option=com_multicategories&view=article&id=660:660&itemid=14". But the link does not seem to work. Can you help me with this?
