I'm trying to play BF3 but it won't let me. Whenever I click play it says to update the game, but when I click on update it just brings me back to my Origin application with all my installed games. Nothing shows it needs updating and it all says it is completely up to date. What do I need to do?
Sounds like a bad install of the update, you could try rolling back and then installing the update again, or i would just uninstall the game then reinstall via Origin.
Try repairing the game by right clicking on it and choosing 'Repair'.
