Draklor Laboratory/67f

Hello, I am stuck in ff12.

I am in draklor laboratory and on the 67floor and exited the elevator. I go left and left again. (To my left I notice a save point) but walk straight on and see the c.d.b. door. When I try to open the door, it gives me the next message. "C.D.B. The door is securely locked."

According to multiple walktroughs I have read, this door should be open and after opening it should give me a key/map/cutscene.

Does anyone know a walkaround of this so I can open the door and continue playing?

I believe there is a key that opens that door, and then you get a key to open the rest of Draklor for domination. As to where it is, just retrace your steps/previous floors.

Yeah, I found that to be the most painful part of FFXII, but it’s great for grinding unless you leveled up a lot before. You will be retracing your steps a lot and the enemies just keep coming.

Maybe I found a clue.

According to the poster of this video. click (http://www.youtube.com/watch?v=8bi33V_L1u8&feature=player_embedded) all the guards are dead on arrival.
On my save all the guards are still alive and attacking me.

In either case, thanks for the support allready.
