Video Player Error with HBO GO

Whenever I try to load a video on HBO GO, I get this:

Video Player Error

This video cannot be played with the current settings of your Chrome browser.  To play this video, you need to update your Chrome settings as shown here: http://helpx.adobe.com/adobe-access/kb/error-3321.html [Code D-1001]

I go to that link and I put hbogo.com in my sandbox thing as allow and it still won't work. What do I do?
