MHFU save data crashed frome 1 second to another

[sanres]

Hi guys, i've got a problem. I was just playing MHFU and i was using version 1.0.1 and recently i wanted to play online so i downloaded version 1.4.2 and kept playing on 1.4.2. The thing is that I had just killed the 2 rajans (last quest from granny) and I saved (not in game cuz from some days back it said no memstick detected) so I always save from ppsspp.

THE PROBLEM is that I had just saved, and like 20 seconds after it crashed (no problem, happens sometimes) so I closed the exe. and then tried to load it and ppsspp crashes and crashes. It's wierd cuz I havent changed settings so I tried loading it on the previous version and ironically it says "save data from an older version" so.... yeah.
What can I do, is the save data corrupt? I have 2 save files close to my finaly save but both have the same problem (load = crash).

I'll add an image so you guys can see
