So I just recieved my M3 Simply along with a microsd card. I pop in the card and transfer files over, then all of a sudden, I get a Windows error saying something along the lines of the file I was trying to move couldn't be moved because it was altered or something. I ignore it, and then try out the ROMs I could copy over. They work, great. However, the problem now is my computer won't even recognize there is a removable storage device when I use the supplied usb reader with the M3 Simply. On top of that, when I try to boot up with the M3 Simply with the microsd card, it locks up at Loading... and never reaches the M3 Menu like it once did.
