I'm having trouble getting that BF4 video to play and the new Metro trailer that was put up. I click play and nothing happens, it just sits there looking stupid. I'm using Google Chrome and I have tried to switch video settings, turned off AdBlock, uninstalled it, reinstalled it. Nothing works. Now if I switch to Internet Explorer *shudder* it works fine.
I am also encountering this issue both on my 4 year old laptop and brand new PC I just built in September. Both are running up to date Windows 7 64 bit home and Google Chrome. I'm assuming @kyotsu and @kaj235 that your computers don't unfreeze and you have to reboot? If so how long have you tried waiting? My i3 laptop takes about 45 seconds to unfreeze then everything works fine while my i5 PC takes about 20-23 seconds to unfreeze. It's weird because after it's had it's "morning freeze" I don't have any issues for the rest of the day.
