But why do you have to attract new users by using a company's figure that is NOT compatible out of the box with the software? And since THAT company decided not to maintain the converter why are you asking on THIS company, instead of using what they have, what is new and is out of the box usable?

You attract new users by showing them what a software out of the box can do. And that is done by developing this software and its features, fixing the bugs that the old owner left in, and making sure the new content they have is usable, pleasing to the eye, morphable and marketed properly with eye-catching and well done demos.
