kicked out on all ISOs

hi, Im really on my edge already on making any of my ISOs work.

Okay, so I have an OFW 3.55, I installed Kmeaw on top of it. I installed the latest Multiman 4.01, installed 3.55 BDEMU KM and lv2.pkg

I opened the multiman, loads a game (marvel vs capcom, zumba, transformers), then the game i chose replaces the icon of my original disc.

THIS IS WHERE IT STOPS.

it just stop.
it kicks out to XMB like nothing happened.

Am I doing anything wrong?
