I'm following the softmod any wii guide and get to the nand backup which i think i'm following but the home brew screen hangs. i have the following files on my Sd card card

armboot.bin
bootmi
ppcboot.elf

which aren't the same as what it says in the guide, i have formatted my sd card before proceeding as well
The guise says i should have these
sd:\bootmii
sd:\nand.bin
sd:\key.bin

I'm a bit stuck now
any help gratefully received.
