Hi gregmalik, thanks for the link! We're very happy people are taking interest in Black Ink. We are totally active and viable (even if a bit busy with Siggraph preparations), just let us a few hours to answer because of time zones But don't worry we do answer and we responded to the activation problem.
As far as I know the Black Ink is completely active, as I get help of this application most of the times during the drawing. I know some times the link is not working, ( I am not sure about the reason) but the link is up and running.
