I have a 3DS with an ace3ds flashcard, and it was running fine. Left it with my sister for a couple months, and I started getting a white screen when I loaded the ace3ds. Then I updated my 3DS to the newest firmware (4.1.0-8), and I started getting a black screen with 'an error has occurred', turn off your 3DS, etc. Can't seem to fix it. Suggestions?
