Hi.

I have a problem on chapter 19 that I can't play!

After Hugo find his mother, there's a place that he must turn the lamp to right to free the rats.
But even when I press D to move the lamp to right, it moves to the left and stop, like flickring.

I can't move on. I already did the chapter all over again and the problem persists.

AWFUL!

What the matter? How can I fix it?
