Hi Doreen, I have one but my gameplay for this particular save doesn't follow the walkthrough. Let me know if you still want it.
Otherwise, did you check the walkthrough directions:
Amateur: Go F, F, F, L, F (173), R, L (121), L, R, R, L, R, R (005), L and F to vent on floor.
Master: Go F, first L, F, R, F, R, L, L, L, R, R, L, L, R, L, L, R, R, far R, R, L, R, L. Go to the vent on the floor.
Remember to move forward until you're able to make your next turn left or right, if you're following the walkthrough directions.
