Hello! I have an Xbox 360 Controller that I just got out of my drawer (being there quite some time, collecting dust) that won't sync properly. I try syncing the controller, and it eventually syncs. But, when I try to turn the controller back on later for more playing, it is unsynced to the Xbox again, and keeps flashing over an over, not showing the Player 1 spot lit up. Also, I keep having a hard time syncing the controller each time I try to use it.
