Hum I'm near to understand the problem, I think.
I made a clear installation, installed DLC, then I delete DLC folder, Online folder and foreign languages folders. The game worked without problem.
Then I tried to make conversion (SP only), data1 and data2 cab has been created without problem, at the begin of creation of data3 I received this error message:
******** D:\Batman Arkham Origins\SinglePlayer\BMGame\CookedPCConsole\Playab le_B
mCash_SF.upk ********
*** ERROR: Unable to serialize 4 bytes at pos=0
FFileReader::Serialize:File=Playable_BmCash_SF.upk <- FArchive::ByteOrderSeriali
ze <- UnPackage::UnPackage
:\Batman Arkham Origins\SinglePlayer\BMGame\CookedPC
Console\Playable_BmCash_SF.upk, ver=99999/0, game=0 <- Main
Unable to find specified file.
Then, after 30 second, the program retry to create Data3 and compression starts normally.
I search in the game directory and the specified file doesn't exsist.
Ok the problem is very strange!! After conversion, the game doesn't work, but I don't install the game from the conversion!! In other words, the game that before conversion works, after conversion doesn't work!! So I think the error mentioned upon "break" any file in the directory and make game unplayable (in particular, game crash during the loading level).
What do you suggest?
