I also have windows 7. I log on through facebook and it works. I also have Chrome but that is not working yet I will try to uninstall and then reinstall to see if it works
In announcements under IT Support there's a message about this issue. No more Flash. It appears we can't play on Facebook any longer and will go to new format available on all devices. They list several. If this is true, why isn't it loading on Chrome? They have no answers while this update disrupts everyone.
