Ocarina doesn´t load from SD?

[Hyper Gumba]

Yeah,I have no USB Gecko,but use Ocarina on a PAL Wii. I used it several times,and it always worked.When I choose Ocarina in the Homebrew Channel now,it stops loading at 0% and I have to pull off the electro wire.
What the hell is wrong now?
Maybe,because I imported MP3s on my SD?

Edit: Thanks it worked very well^^

Remove any GameCube Memory Cards, and try to load it again.
