Flash does not work on Chrome browser.

All embedded flash objects for all of our client websites have suddenly stopped displaying in the past three/four days.  I haven't changed anything that would cause this.  It isn't a problem having to do with Chrome/Flash Browser settings because the missing flash is seen on three of my computers.  There are are issues with Firefox and Internet Explorer.  Anyone else having these problems?  I have tried to find out on my own but can't come up with a reason or a fix.  I'm pretty desperate because I know that tons of my clients use chrome and if I don't get a fix I'm going to have to take out all of the flash components and go back to static graphics/objects.  Help Please!!!!
