It's gotta be something you just now changed because they were working fine just an hour or two ago.
At the moment, literally any Flash submission I view just has a big blank space where the animation/game should be. Also none of the ads or anything shows up either. It's just blank spaces where all of the content should be. It doesn't even load (If I right-click I get the context menus as per a regular HTML page and not what you would get from Flash)
