Error setting up player: Invalid License Key
I'm actually having a problem viewing websites that have JW Player videos. I take online classes and that website uses a Jw Player and the video shows up black and says "Error setting up player: Invalid License Key." (Kelbyone.com) I've accessed the site on someone else's laptop and was able to view it. On my computer, I went to JW Player homepage and the player says the same thing. I've tried in Safari 9, Firefox 41 and Chrome. Flash is updated. I'm on a Macbook Pro using El Capitan (I updated to El Capitan thinking that might be the reason I'm not able to view it....it's not). I've cleared my cache and cookies and still nothing. I contacted the website and they said it's nothing on their end. Why can't I view JW Players?
