Did you hear jets flying overhead or the Star Spangled Banner playing? That's what happens prior to stations going off the air. But it's pretty early for that still. :biggrin:
Update your video drivers, do a clean install of them and download the latest k-lite codec pack to be sure your system is most up to date for playing content with overlay. If that's flash make sure that's up to date. Disabling hardware acceleration (right click if it's flash and the menu has it there) may also help, again if applicable.
