Is there any type of training currently provided for Arbortext Styler

The first link provided does not appear to include Arbortext in the Catalogs of Live Courses.

I have looked at the “tutorial” provided, but it seems to just describe the menu options, but does not really provide instruction for “how  to”. 

I purchased the book  written by the single-sourcing people, but is written for a dita structure, my book is a docbook. Additionally, I did pay $100 (of my own money) for a 30 min. session with them, where the first 10 min. included trying to get the screen sharing to work. They did seem to be knowledgeable but said the stylesheet we are using was built incorrectly and since we’ve run out of time, they suggest scheduling a full session which costs $2500. My company won’t pay for this.
