I just recently purchased an AceKard 2i, been enjoying it for a little under a day. I wanted to try and connect to the internet to check something on google, and when I loaded up the Opera Browser, the DS froze. I turned it off and then back on, and all I get is the message: "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." Now, the browser has worked for me before, so it leads me to think that it was because the Acekard was in the slot. I currently can't do anything with my DSi, so if anyone has any suggestions, I would be appreciative. Edit: Things that have not worked: Booting the DSi with the Acekard Booting the DSi without the Acekard Booting the DSi with several choices of retail games Removing the battery for a long period of time, then booting Will try for longer this time.
