I have a new 3DS XL running 11.2. I followed all the steps on 3ds.guide and get where I put the MicroSD card in and launch 3ds Sound. If i do it with the power off, I just get a black screen and nothing happens. If insert the card with the power on it freezes. When I remove the card with the power on, it starts working again, except it says, "Please turn off the power before removing microSD cards. Any idea what is wrong?
