Help Installing the Homebrew Channel on my Wii Through Smash Stack?

I went to wiibrew.org and followed the directions. I renamed the sd card's private folder to privateold. I downloaded smash stack and saved its private folder under wii, then app, then RSBE, then st. I downloaded hackmii version 0.8 and put its boot.elf file in the same section as smash stack. I got rid of the rest. I deleted all custom stages off the wii and the sd card. The sd card is 1.0gb. I put the sd card in my wii, turned on Super Smash Bros. Brawl, and went to stage builder. Nothing Happened!!! It didn't load. It didn't do anything. What did I do wrong? Please Help!!
