Ahhhh .... i had the same problem ... moment .... my brain xD ... i found a solution ..... .............
okay try this:
First Update your Browser what ever you use
Be shure thats your graphic card drivers are up to date
For Nvidia drivers LINK
For ATI drivers LINK
Than login into your battlelog account and launch game, try this on different browsers (Internet Explorer and Firefox)
I hope this helps
