\Beta not defined

[ProfNitz]

I just downloaded 1.60.2 and it seems that \Beta is not defined (all the other capital greek letter work fine)

sample code: \documentclass{article} \usepackage{amsmath} \renewcommand{\d}{\mathrm{d}} \pagestyle{empty} \begin{document}

\begin{align} \delta &= \Delta\,\mathrm{e}^{st}\ \dot{\psi} &= \dot{\Psi}\,\mathrm{e}^{st}\,\, \mathrm{mit}\,\,\dot{\Psi} = G_{\delta\rightarrow\dot{\psi}}(s)\Delta\ \beta &= \Beta \end{align}

\end{document}

error message ! Undefined control sequence.

...{\psi }}(s)\Delta \\ \beta &= \Beta l.12 \end{align*}

This is a LaTeX issue, not an IguanaTex issue. Some uppercase Greek letters are not defined, please see this StackExchange question. \Beta is simply \mathrm{B}.
