Hello all, I'm looking the reason of non-functioning my context module in the context TeXlive 2010. In context mimals version everything is working properly and without error, but when I compile my source code with ConTeXt, which is part of TeXlive 2010, then I get message: C:\1da\ConTeXt-MkIV\t-scancsv.mkiv>context --autopdf cykly-test-002.tex MTXrun | run 1: luatex --fmt="C:/Users/Jaroslav Hajtmar/.texlive2010/texmf-var/ luatex-cache/context/da91aab37cf8e89a658f7077fc24d4ff/formats/cont-en" --lua="C: /Users/Jaroslav Hajtmar/.texlive2010/texmf-var/luatex-cache/context/da91aab37cf 8e89a658f7077fc24d4ff/formats/cont-en.lui" --backend=pdf "./cykly-test-002.tex" This is LuaTeX, Version beta-0.60.2-2010071421 (Web2C 2010) (rev 3736) \write18 enabled.
