Well, it seems as if the org-babel-tangle-file call in
org-babel-load-file returns nil, but it's not clear why.

Do you have an emacs that is sufficiently healthy so that
you can evaluate things? An emacs -q perhaps with a minimal
init file that will set up org?

If so, go to its *scratch* buffer and try evaluating this:

(org-babel-tangle-file
"/Users/fullofcaffeine/.emacs.d/fullofcaffeine.org"
"/Users/fullofcaffeine/.emacs.d/fullofcaffeine.el" "emacs-lisp")

It should return

("/Users/fullofcaffeine/.emacs.d/fullofcaffeine.el")

Does it? Does the file

  /Users/fullofcaffeine/.emacs.d/fullofcaffeine.el

exist?
