Hacking I'm 90% there! I only have 1 more question!

[ChristopherMims]

I used WBFS Manager to put Wii ISOs onto my 500 gb partition (F) on my 1tb Iomega external hard drive. I have a Wii 4.2U, with all of the stuff installed correctly.
USB Loader GX:

• I opened USB Loader GX from the Homebrew Channel
• I went to Settings>Unlock, and I typed the code (ab121b)
• I clicked OK, and I message popped up, saying that install, rename, and delete are unlocked
• I clicked OK, and when I click "Go Back" to return to the menu, the button freezes. I can still move the cursor, but the buttons stop responding.

I then tried the Configurable USB Loader.

Configurable USB Loader:

• I opened Configurable USB Loader from the Homebrew Channel
• Everything loads correctly.
• When I click on a game (i.e. Sing It: Pop Hits, for my little sister), it plays the title music, and says the name of the game
• After I click on "Boot ISO", it lays "Loading. Please Wait...", but just freezes there.

Can anyone help me with any of these problems?
