I am having the same problem others had the last few years. This is their thread: http://forums.adobe.com/message/4819672#4819672
Everytime I load a NFL video running nflvideoplayerflash 3.9.2 build 3.9.1 (which is all of them) It gives me the loading screen then loads a grey screen, with a pause/playbutton, fullscreen button and the quality bar. but just grey screen with NFL logo in the upper left hand corner.
Running Windows 7 Ultmate, SP1, Google Chrome, all updated drivers/flash player
Every other place that runs flash has not been a problem, and up until a week ago, neither was NFL.com. But now this.
Can anyone help with this?
