I just got my DS Lite to work again and I am really into playing Digimon World DS. The problem is whenever I try to save, it doesn't work and gives me the message "Could not write data. Turn off power and reinsert the DS Card". When this comes up, I also can't go back or anything so I'm forced to turn off the DS. I can play the game without running into any problems; the only problem is the saving. I've tried many times and this keeps happening. If anyone knows what the problem is, how to fix it, or has fixed it, can you please help me? Thanks.
