after playing 1st video no other videos will play

Hi – I have several videos installed with several images in between them. After I play the first video and try to play the next video – an overlay comes over the page and a box with a left & right arrow up at the top of the page but does nothing. No video comes up in a lightbox and I have to click on the overlay to get it removed. In order to play more than 1 video I have to refresh the page.

I disabled ALL other plugins and it still does the same thing.

Any assistance you could provide would be greatly appreciated.

Thank you.
