I apologise deeply if this has already been covered. I did look at the Troubleshooting forums but I couldn't find my problem exactly, I am lazy when it comes to looking for things.
My problem is that every time I open my map to edit it an error screen appears, I have posted a picture of the error*. I purchased Amnesia: The Dark Descent from Steam and downloaded HPL Editor Suite from the Wiki.
For more information read the posts on the thread.
EDIT: I have now attached the Error log in high hopes that it makes the problem more clear.
