Mathcad for FIRST teams?

Hi,

I'm a mentor of a FIRST Robotics Competition team, and I'm interested in trying out Mathcad as a teaching tool.

I'm clicking around everywhere on the website, and I can't quite figure out how to get the free Mathcad PRIME 3.1 for FIRST that these pages indicate is available. Any help is appreciated.
