Previously I had been using DVD / CD Ver 9 and finally upgraded to 2015. When I attempt to invoke the transitions, they do not preview nor do they work.  for instance, if I select a cube, slide A goes blank, then slide B appears. The cube affect is non existant. Same thing with other transitions, such as turning a page - it blanks out rather than turns the bage. Any ideas what I can do to make it work? I feel like I wasted $50!

Thanks....
