Hi all, My mac can't 'see' my micro SD card. It was fine, then i loaded the r4 software onto the Micro SD, placed it back into the r4, then the DS and it then crashes on the selection screen... Now, when I put the card back into the reader and then into the computer, it can't be found on the computer anywhere, just does not recognize it. any ideas? Guessing i need to reformat it and start again, yet with the card not being found it's rather tricky to do so. Regards.
