I bought my controller a week or two before Halo 4 came out. It is the Limited Edition Halo 4 controller and as of yesterday (3/20/13) it won't connect to my Xbox. All of my other controllers connect fine but it turns on and won't connect to my Xbox. I've tried syncing it multiple times but it won't connect. The batteries are fully charged and there shouldn't be anything around the Xbox that would effect the interference, I'm within 5 feet of my Xbox. Please respond if you have an idea how to fix it.
