Did you add tikz to org-latex-packages-alist?

I always go back to straight LaTeX to debug such problems:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\tikzstyle{astate} = [circle, draw, text centered, font=\footnotesize, 
fill=blue!25]
\tikzstyle{rstate} = [circle, draw, text centered, font=\footnotesize, 
fill=red!25]

\begin{document}

\begin{tikzpicture}[->,>=stealth', shorten >=1pt, auto, node distance=2.8cm, 
semithick]
\node [astate] (1) at (0,0) {1};
\node [astate] (2) at (1,0) {2};
\node [rstate] (3) at (2,0) {3};
\path (1) edge [bend left] node {b} (2)
(2) edge node {b} (3)
(2) edge [bend left] node {a} (1)
(3) edge [loop above] node {(a, b)} (3);
\end{tikzpicture}

\end{document}
