Maybe this is my fault. The simpleslides module works just fine these days
and I "accidentally" updated the ConTeXt to the latest version:

context --version

mtx-context     | ConTeXt Process Management 0.60
mtx-context     |
mtx-context     | main context file:
/opt/context/tex/texmf-context/tex/context/base/context.mkiv
mtx-context     | current version: 2013.02.13 18:06

and this small piece of code failed to compile:

\usemodule[simpleslides][style=BigNumber]
\starttext
\SlideTitle{Test}
test
\stoptext

and gave me the following error message:

simpleslides    > loading Big Number style

there're more and if it is important for the diagnostics please let me know
and I will provide the whole message which I thought was relevant.


Anyone can confirm this?
