So when Animal Crossing NL first came out I had my sister pay and download the game onto the system. It didn't have any network id or a nintendo club id. Up until now,9/23/14 I had signed up for a nintendo club id. When I did all the downloaded game on the system like Animal Crossing NL and Super Smash Bros. 4 Demo got deleted. I then went into setting to see if the games were still there, they weren't. I then tried the eshop, wasn't there either. I thought that my SD card got corrupted when I signed up for nintendo club, move the data to my desktop, reformat, and move it back in but to my surprize, nothing. When I downloaded Animal Crossing NL I had thought that the game was in my console forever until I deleted it from it, I was sadly mistake. When I created my nintendo club id, everything was lost, including Mii Plaza update. I reupdated my Mii Plaza and everyone was still there, sadly my game are gone forever because I signed up for nintendo club. Anyone have any suggestion what I should do to fix this?
I created a nintendo network id to get the demo but then unlinked it because it was annoying to handle. The conformation email never came so I didn't want to bother with it. I have not yet called nintendo about this because of the time. If I were to give them my 3ds system code will they be able to track it and find the purchase or will I have to give them my sister credit card id to find the game?
