Data Generation Plan Missing from VS2010 Pro

I was following this tutorial

and I got to the point where I am should add a data generation plan file. Yet when I click on the folder there is not data generation plan file. I don't know why. Do I have to install it separately or what?

Or is it because I am using 2005 express?

Data generation plans are apparently only available with VS Premium and Ultimate.
