video in overlay will not play in https pages

I recently installed https on my site and the video I used to have playing in overlay will not run, I just see the overlay. Checking my console I see error saying that the plugin is trying to get the video from an http url rather than https. I am assuming the content is blocked because of that.
I have gone over the plugin code and not found how to fix this. please help.

My site is singlecue.com and in the top frame there is a link to watch a video. You can click it to see.
