Returned! (Ret = -1) Error

Before hacking ever entered my mind I updated my Nintendo Wii to a 4.3u. Yeah I know...DUMB. Anyways after failing attempts at hacking I downgraded it to a 4.1u so there has been some progress. I'm not new to the hacking business any more but every time I finish the arduous progress of wads and cios's and all of this stuff I finally get to one of my usb loaders and when i go to play a game....

I get this error====> "Returned! (Ret= -1). :(

Does anybody know what that means?

And what I can do to fix it so I can play my games from my usb.

(I'm using Configurable USB Loader right now and have all the ci0s's installed 9-20)

Thanks!:)

Get a trucha patched ios 60, I think. Alternativly, used google. :P

ALso, discussion of the USB loader isn't allowed...

Why would you downgrade in the first place?
