Hacking Problem with UNO exploit

[Deferet]

hopefully someone can help with this, I installed the UNO exploit and I am able to play csos and isos with no problem, but every time I try and play an eboot it gives me "An error has occurred. (C1-2858-3)"

I've tried several times with different files, I've tried an snes emulator and some psx eboots and I get this error every time. I don't know if it's something I'm doing wrong, I've read the tutorial on http://wololo.net several times, I use only capital letters on my files and folders, and I use the file system PSP/GAME/SNES/EBOOT.PBP and I use winzip to zip the file.

Is there anything I'm missing? Is this happening to anyone else?

I apparently forgot to load the popsloader
