EXCEPTION_ACCESS_VIOLATION Crash - Solved

[WhatevaGuy]

Forgive me if this is a repost, however I did use the search feature, to no avail.
Amnesia has worked fine constantly, up until this point. I am trying my hand at making a custom map (it's a very simple map, and rather silly, but I like making things) and for whatever reason, I can't get it to work. :c
When I attempt to start up the custom story, I am presented with this:



My guess is that it's some sort of problem with OpenGL (atiogl, ATI is my graphics card; ogl is OpenGL) but I know nothing about computers.
An added note, any other custom story works perfectly fine for me.

I have included, as an attachment, my custom map (to my own embarrassment; it's not very good and I certainly don't plan on releasing it any time in the foreseeable future unless I improve it) and, as pictures, my computer specifications.

The HPS log is also included, although I'm not quite sure how much of this is actually necessary :/

Any help would be much appreciated. Thank you!

Tried the game itself runs?
I think it's a map issue rather than driver issue.
Plus, check that if you correctly set up developer environment.

[WhatevaGuy]

The game itself does in fact run.

Oh? If that's the case, do you have any idea what could be wrong with it/how I may go about fixing it?
Alright, I'll check.

Completely re-setup the devenv and the map loaded, thank you! I'm not sure what I did wrong. Thanks!

It was most probably the dev-env setup, because I have three trial-error thing to go over and finally achieve. That's because I'm stupid, you might be a little distracted while setting things.
