Black screen when trying to do homebrew

Ok. So i followed this guide step by step ~ http://wiibrew.org/wiki/Homebrew_set...ii_Through_HBC I installed everything, my folder looks exactly like that, and i did the nand backup thing. So now i'm at the 4 button screen or the hbc screen, whatever it's called, and when i click the homebrew button nothing happens..just a black screen shows up and won't let me turn the power off or go back. I probably shouldn't have but the only way to turn it off was to take the cord out the back, so i did that and the wii still came back on, no problems. I tried again and the same thing happened.
The pic below is what my sd card looks like right now. This is my first time doing this and i really want this to work.
