I don't know why but when I tried to load a game on my wii from usb (using configurable usb loader) it loads to the screen showing to put the wrist strap on and then the screen turns black. It then either freezes the wii or crashes back to the main menu. My wii was working fine last week so I don't know why this has happened. I have a nand backup and bootmii installed but not as boot2. Someone please help.
