Cryptographic Sequence in "Batman: Arkham City"

Hi Game Spot!

Suddently I'm trapped(not bugwise) and to get out I seem to need a Cryptographic Sequence I don't have. So is there another way to get out? or if I have to find in a previous level what level was that and where was it(location wise)?

Thanks in advance.

The Cryptographic Sequencer is a piece of equipment you get in Arkham City that you use to hack various terminals throughout the game. Where exactly are you stuck (i.e. where in the city, what mission are you on, how far into the story, etc)?
