Thank you for your job and sorry for my little bad english knowledge

I want to localization the prince of persia 2008 XBOX360 game.
The assassin_creeed2.bms was perfect to extract the LocalizationPackage_English file, but when i reimport the extracted file with the same script, the script asks for me:
Do you want to use the experimental reimporting of chuncked MEMORY_FILE <y/N>?
If I choose the NO, the method is running ERROR:
54 log MEMORY_FILE OFFSET SIZE
If I choose the YES, the method is working, but the reimporting file is almost empty...not valid LocalizationPackage_English file.
Aluigi, can you help me for this problem?
Thank you
I attach the original file
