Creating an SFML Window causes my Application to crash

Hello, I have been following the Beginner's Tutorial 2 of the OGRE wiki. I wanted to customize the code by trying to make the "ninja" in the scene move when I press the U button

The user-input is supposedly being handled by SFML.

As far as I know, the Project is able to Build without linker errors, however, the application crashes the moment It tries to load the 3d scene after the dialogue for setting the graphics.

It gets the Buffer Overrun error dialogue

I was able to deduce that the problem occurs when I try to create the window for SFML. With the sf::Window line of code gone, It is able to work properly, as shown in my code
(note: I placed the event-handling code within comments to prove that the application crashes on the line that is supposed to create the sfml window for user input)

What is disabling my application from handling user input properly? Can it be solved? Do i even need to create an SFML window in the first place for user-input? How do I solve this problem?

I'm stumped, SFML has been a roadblock in my quest of handling user input. The OGRE tutorials are much more bearable since they teach me how to setup the project and insert the code, in my opinion. I wonder if i should still use SFML after this experiment of mine....

Cheers.
