Save skinte pliz! (Batman: Arkham Origins - Blackgate)

After passing the traps the Joker, where you have pairs batarang to disable the target, I reached the drawer with shock betarangom and took it, after the computer crashed. After a reboot appear in front of the trap down, but no aiming betarangom. The door is closed.
Ago also not to return.
Throw the saves before or after, pliz. And how to deliver them, accomplish your goal.
Thank you.
