It may have happened a long time ago. I just updated my context and could
not compile my document with \setupbodyfont[lucida], something like:

===========================================

Last time I saw this message, I was preparing a document in a hurry so
I just download an old cont-tmf.zip and it's okay again.

I got a font AdobeSongStd-Light.otf and after
==========================================
mtxrun --script fonts --reload
==========================================
I still could not find it:
==========================================
Zhichu@ZHICHU-PC /context/tex
$ mtxrun --locate AdobeSongStd-Light.otf
tree:///d:/ConTeXt/tex/texmf-fonts/fonts/opentype/public/Adobe/AdobeSongStd-Light.otf
Zhichu@ZHICHU-PC /context/tex
$ mtxrun --script fonts --list --pattern=Adobe*

Zhichu@ZHICHU-PC /context/tex
$
==========================================
Well, can you give me a hint what's wrong here?
