BCC particle illusion dont upload video

Hi my friend bought BCC plugins recently, but we have a problem with uploading videos in bcc particle illusion. So when we insert this effect on a video in premiere pro, and run particle illusion we only have a black screen and effects without video. Can you please help me with this ?

No need we found a way to solve the problem, if someone needs, above the place where the video is loaded on a rectangle where it says Preview Background, he should set the option Composite Over Source Video
