[O] Somehow orgmode doesn't export code to pdf in MINTED environment!

[address@hidden]

Hello, 
I've already posted a few days ago on my MINTED problem. On someone's 
suggestion on this mailing list, I cleared up my init file and only left the 
following settings:

---------

 (server-start)
; (add-hook 'LaTeX-mode-hook 'turn-on-reftex)
 (setq reftex-plug-into-AUCTeX t)

;;; a key for tilde symbol
(define-key key-translation-map (kbd "M-2") (kbd "~"))
;;; a key for backquote symbol
(define-key key-translation-map (kbd "M-6") "")
(define-key key-translation-map (kbd "M-9") (kbd "`"))
;;this one's only for CDLaTeX math insertion
(define-key key-translation-map (kbd "C-1") (kbd "`"))

;; visual line word wrapping
(global-visual-line-mode t)

;;automatically recognize org files
(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))

;; MINIMAL init FILE 

(add-to-list 'load-path "~/src/emacs/org/org-mode/lisp")

(require 'org-loaddefs)
(require 'org)

(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))

(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-cc" 'org-capture)
(global-set-key "\C-ca" 'org-agenda)

;;; 

(setq org-latex-listings 'minted
  org-latex-packages-alist '(("" "minted"))
  org-latex-pdf-process
  '("pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
    "pdflatex -shell-escape -interaction nonstopmode -output-directory %o %
f"))

(setq org-latex-minted-options
   '(("fontsize" "\\footnotesize")("bgcolor" "white")("obeytabs" "true")))

;; -shell-escape for minted pkg (COMMENT WHEN NOT IN USE)
(add-hook 'TeX-mode-hook
  (lambda ()
    (setq TeX-command-extra-options "-shell-escape")
  )
 )
;;;

---------


The above is my ENTIRE .emacs file. There's nothing else on it beyond those 
lines.
After this tweak, all was working fine but today the problem has come up 
again. I DON'T KNOW WHY! Essentially, when going from .org to .tex, it exports 
the contents of #+BEGIN_SRC inside LISTINGS environment, not MINTED, in spite 
of being told to do so! 

This is the minted.org file that I'm trying to export to pdf via .tex (C-c C-e 
l o). I'm on a 32-bit Windows 7, emacs 24, org-mode 8.2, TeXlive 2015 with 
MINTED package and pygmentize correctly installed. Sumatra as pdf viewer.
