I had the same problem. It had something to do with allowing ffdshow to be used. I suggest you download this package www.cccp-project.net/ , When I installed it I automatically got the opportunity to choose between four different options about using ffdshow when I started the trainer. Choose the option " Use ffdshow (always) ".
I hope this will help you, its worth a try. Good luck man.
Edit: If you try it out let me know if it worked please
