opcvop, here are two links that may help you:
First link Second link I certainly hope that those can be of help and that you can compare their pictures and the ones from the WT with yours.
I remember that when all four proper round turning plates where in place that it was still a long process going up and down the elevator to level 1 and -1, but at one point you will learn how to turn them properly.
Do not forget that you have three exits to work with, not counting the entry.
The best of luck.

EDIT: I do not know how you can reset your game to the moment you got there, unless you still have a load game to download from a previous save and that you can replay from there and get to the elevator.
