Danganronpa Kibou no Gakuen ro Zetsubou no Koukousei (PSP The Best)

[Air96]

My problem is that when I'm at Chapter 6 of Danganronpa, when the investigation starts and I have to investigate all the room.
when I reach to the data processing room, talk to Asahina and entering to the monokuma door, suddenly the game crashes and when I see the report of the computer, there says AppCrash. I played again that part and the same problem ¬¬ AppCrash so before the crashing part, I saved and loaded the game, but when the loading menu pops up, the PPSPPWindows has a problem and crushes... I've restarted the computer, everything but the problem is still freaking out to me I was almost reaching to the final part...
