"10B. Put your SD Card into the Wii, launch Brawl through the Disc Channel, and go to the Stage Builder.
11. When the HackMii installer shows you what can/can’t be installed, hit continue. Go to Homebrew Channel > Install the Homebrew Channel. Hit “Yes.”"

This doesn't work for me, the HackMii installer never shows! Everything is normal in the game. :S
I have PAL, 2 GB Transcend SD-card, and menu 4.3.E. Could someone help me?
