MiKTeX package expl3 (for l3kernel?) is too old

[Dave94705]

After making sure I am fully up to date according to MiKTeX' updating module, I LaTeX PDFed:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{datavisualization, datavisualization.formats.functions}
\usepackage{animate}

\begin{document}
\begin{tikzpicture}[domain=0:4]
\draw[very thin,color=gray] (-0.1,-1.1) grid (3.9,3.9);
\draw[->] (-0.2,0) -- (4.2,0) node[right] {$x$};
\draw[->] (0,-1.2) -- (0,4.2) node[above] {$f(x)$};
\draw[color=red] plot[id=x] function{x} node[right] {$f(x) =x$};
\draw[color=blue] plot[id=sin] function{sin(x)} node[right] {$f(x) = \sin x$};
\draw[color=orange] plot[id=exp] function{0.05*exp(x)} node[right] {$f(x) = \frac{1}{20} \mathrm e^x$};
\end{tikzpicture}

\end{document}

and got the below error and crash

! Package l3regex Error: Support package l3kernel too old.

I assume if I wait awhile this should be solved, but thought I should note it in case others are having similar problems. ds

Run the MiKTeX Update Wizard both in 'Admin' and non-Admin modes.
