I just recently got a problem with my DSi. Right after I downloaded the DSi transfer to 3DS app from the DSiWare store I turned off my DSi and then when I turned it back on the screen went black and on the bottom screen it says: "An error has occurred. Press and hold the Power Button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting." I did that several times and got the same message. I searched the error online and all of them related to R4i and Acekard situations...but I don't have one of those. The game inside the cartridge is Pokemon Black that I bought from WalMart. Anyone have a fix to this problem?
