My system worked fine on monday morning. I took my controller to my nephews house and synced it to his xbox360 as the # 2 player and it worked fine. The next night I manually turned my 360 on and tried to sync the same controller and nothing happened. I have done this before many times and I have never had a problems. I replaced the batteries, unplugged my 360 for a few minutes and tried again. NO LUCK....any advice?
