I am having trouble with displaying video on my blog site. I have a Videopress subscription, and the files played OK for a time, but now they will no longer play. When I first add them to a page I can go to the page and they play OK, but when I close the browser and go back to the page they no longer play. I have check with other browsers, on other machines, and on other networks and they don't play on any of them. I contacted customer support and they have not been able to help me. This is my company website, and I really need a solution. Thank you for your help.
Here is a link to a page with a video on it.
The blog I need help with is exhibitwise.wordpress.com.
