How to build a custom class?

[coastiemike]

I bought a copy of the Hero Lab at Gencon this weekend. I have it installed and am trying to tweak it by creating a custom character class. I have a player who has a Beguiler in my Pathfinder campaign. Beguiler is not a class in the Pathfinder system so I would like to "build" or copy the beguiler class from 3.5 rules set and make some changes to reflect the Pathfinder rules.

How do I get to the create custom class screen? Is there a way to import my created custom beguiler class to my Pathfinder licensed Hero Lab?
