Our Xbox 360 controllers had their batteries die and where replaced. Now upon console restart it is prompting whether we want to proceed with a system update. Unfortunately the controllers are now not synced with the console so with controller we can't answer yes or no. We're stuck at this menu. I've tried re-connecting both controllers, but the system does not appear able to accept new connections at this menu. Any suggestions on how to proceed? Buy a wired controller and try?
