Amnesia just stopped working

[Robby]

It cannot be empty if the game ran fine a month ago according to your post.

In my situation, the hpl.log would be located in (C:\Users\Robert\Documents\Amnesia\Main). In your case, it should be the same, except the username is different (Instead of Robert, it would be your username).

Just 'attach" it. We need to see the log itself.

Also, while you're at it, post your PC's specs.
