I just got the game yesterday, and I love it, but I am stuck. I am in the GCPD building looking for Mr. Freeze, right after you subdue some henchmen. I am locked in two rooms that are separated and I have to use a grate in the floor to access each room. There is a secruity panel on the wall in one of the rooms. I am being asked to utilize the cryptowhateveryoucallit sequencer. It is blinking on the screen showing me which one it is, but Batman cannot access it. Any help would be greatly appreciated.
