I just bought the card and got it today from modchipcentral.com. It was supposed to be installed with the latest firmware already, so I just copied the most recent EOS system onto the SD card per the instructions that came with it. When I put it in the 3DS it came up with an Alex Rider icon, however whenever I tried to open it I'd get "An Error has occurred" message telling me to turn my system off. However, it loads just fine in my DSLite. So far I've tried reinstalling the firmware on the DSLite, reformatting my SD card and installing the EOS again per the guide on this forum, and putting some paper in the DSTwo card behind the contacts to move them closer. Nothing is working. Does anyone have a clue what the problem could be?
