colortbl conflict with tabular parbox?

Question

I have a large document that I want to fix column widths in several tables and I have previously done so using p{XXin} column types (where XX is some number). I recently moved to a new computer and therefore a new MikTex installation. My document now fails to compile when it hits the first tabular environment with a parbox column. This only appears to happen if I also call colortbl.

Here is my MWE:

\documentclass[letterpaper,12pt]{report}
\usepackage{array}
\usepackage{colortbl}
\begin{document}
\begin{tabular}{|p{2in}|l|}
1 & 2 \\
3 & 4 \\
\end{tabular}
\end{document}

I realize that colortbl already should call array, but left it in to shown that it works if you comment out colortbl.

Is this a known issue, or has something been deprecated and I need to change how I handle this? I'm guessing that my old machine was running on packages that were several years out of date.

EDIT2: Here is the first error running pdflatex returns:

Use of \@startpbox doesn't match its definition. \begin{tabular}{|p{2in}|l|}
