Savegame extractor

I've tried using the savegame extractor by Waninkoko and I get an Error! (ret =-1)

I do have a legit game, I bought it new yesterday at gamestop :D
I bought a used wii and it had system 4.2 currently installed
I installed homebrew using hackmii and the bannerbomb exploit, I did NOT install the DVDX or Bootmii (I don't know if this is causing my problem)
I installed the savegame extractor and savegame installer using the homebrew browser
I also tried installing the savegame manager, but all I get is a black screen
I attempted to install the cIOS patchmii for the manager, but it wouldn't recognize it for me to run it
I AM using a usb device as opposed to an sd card and it is formatted in FAT32

I hope I've provided enough information. I've searched and searched and it seems as though this method has worked for others, but I just can't seem to make it happen.


EDIT: I was able to save the game without the error when using an sd card, so I guess that's just what I'll need to do. It's not my prefered method, but if it works it works. Perhaps someone has a suggestion for using USB devices?

Before I read the edit, I was gonna say use a SD Card :P

I don't believe there is any USB support :/ sorry.
