I have the same problem. It's in the Style Picker window at the bottom of the New RTs list on the left side. I think it's supposed to be a part of the "Bonus 10 Pak". Read Me for the Pak says it needs a separate install, but there is no install program for it (like there is for Loops).

Was going to ask the same question or email support, but never got around to it. Had to Christmas shop.
