Videohive doe not work with FCP X 10.2.1?

Hi, I need your help regarding this product. I bought the Videohive tranistions etc. to use with Finalcut Pro X 10.2.1, unfortunately none of the transitions or titles work. I am using an Imac 2009 with Yoesmite OS. Before I bought these, I read in some forums that it will still work with FCP 10.2 but some transitions wont function.
