[FancytheKiller]

Hello, I have a xbox 360 wireless receiver and just recently it dosent let my controllers connect, I plug the receiver into a usb slot, press and hold the power button on the controller and it just flashes on and off. This is the case with 2 controllers and I dont know what is causing this. Any help is greatly appreciated, thank you.
