I don't know what happened. I plugged it in for a while, then unplugged it to play it. When I plugged it in again, it charged for I don't know how long, and just stopped. All that I can remember doing that I've never done before is left the charger in the actual 3DS while playing it plugged in. I can't get it to work with the dock or with the adapter plugged into my 3DS. Help would be appreciated. Also, I'm on vacation now and can't just buy another adapter. Thanks.
