Hmm, and the file within the game folder is game_scripts.rpa? It's not the ZIP'd file of the game_scripts.rpa, right?
The other two suggestions I have: Make sure nothing else is in the game folder. On my phone I had an old patch still in there - Make sure the only file in the game folder is the game_scripts.rpa file.
Also, of course, you need the Days 9-11 APK. Elysium or Endurance edition. The old Days 1-8 APK won't work.
