More than 2 popups on a page doesn’t work with PRO version

I purchased the PRO version and have tried using it to pop up a video when user clicks a button – there are several videos listed. It works ok if there are only 2 but the minute I add the code to a 3rd option, it no longer works. If you popup the video, you can’t get out of it by clicking off the video or clicking the X to close the box. If this can’t do more than 2 videos, I need to request a refund. Otherwise, would love to know if there is another trick to this that I’m missing so I can give a good rating.
