Red Giant Universe Transitions giving error on render
 

I'm using the Red Giant Universe Transition plugins in Premiere Pro CC 2015 9.2 and although they work fine when I play the timeline they are giving a "Error Compiling Movie - Unknown Error" message. When I remove these transitions things start working fine. Anyone else having these issues? What could it be?

Also, any recommendations for other alternatives? I hate all the stock transitions that come bundled with PPCC.
