I cannot move in level editor. Why?

[Slanderous]

Hello everyone,
I have a big problem with level editor for Amnesia. Since a week when I try to move in level editor using W,A,S,D the camera does not want to move. I tried to reinstall the editor THREE times and it still won't work.
Anyone can help me with that?

BTW. Sorry for my every grammar mistake, my english isn't perfect.
