At first, please check your latest video-card driver and check what version of the origin client is installed on your computer. Install the newest driver for your video card. Right click in Origin under "my games" on the Battlefield3 icon and choose "Repair".
Clear your browser cache and/or try a different browser. Reinstall your webplugins for battlelog.
Try to deactivate your firewall/antivirus software and/or check the online ports of your connection:
TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.
Please let us now, if this problem after this workaround still exist.
