Hi, I recently bought the HD trilogy but I'm stuck on what I think is a glitch. I get inside the police station, into the computer room guarded by the man with his back to you. I take him out then use the computer. I think someone is supposed to come on the mic and I can then leave? But nothing happens. I've been inside the interrogation room and the room with the camera. I've replayed it several times and even re installed. Am.I missing something? Any assistance will be greatly received.
