I get the message "Save data file Fromat error!" every time I try to load any game. And yes, it says "Fromat." Also, I tried putting the memory in my computer (Macbook Pro) and it doesn't even recognize it anymore. I imagine I can fix the error myself but I can't seem to find a way to get my computer to recognize it. There is nothing wrong with the USB port itself, and it has worked fine before. So, can anyone offer any suggestions? Is it just not compatible with the Macbook Pro and the last times were flukes? Do you think something is wrong with the memory card itself? Thanks in advance.
