Brawl EX on a hackless Wii Problem.

[Smashball2011]

I'm trying to use Brawl EX for the first time for a hack I'm working on, and I tried to make a clone of Mario and followed all the instructions in this video:

I placed all that I needed into the SD Card, and I launched it via the Stage Builder launcher, and upon selecting the clone for Mario (who I'm working on as a test), the game freeezes.

I don't know what to do here, so if anyone can help me out with this, I'd appreciate it, since this is the first time I'm using Brawl EX
