hi i downloaded update 1.19u, yes i know it was unofficial and i was using it at my own risk. it works fine, but i wanted to put the old version 1.18 back on (i backed up all my data before doing this btw). so when i put my memory card into the usb reader and plugged it into my mac, its not showing up. my drive is not showing up at all. i tried it on my other mac as well with the same result. the memory card still works in my r4, but unless i can get it to work again i wont be able to put new games on there, let alone switching the software back. does anyone know what i might be able to do to fix this? thank you!
