Hello, I'm getting the following error: " mtx-context | run 1: luatex --fmt="c:/Ctx-Beta/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde... iv" --c:kindofrun=1 --c:maxnofruns=9 --c:nonstopmode --c:path="C:\\Lukas\\ConTeXt\\Styles" "cont-yes.mkiv" This is LuaTeX, Version beta-0.80.1 (TeX Live 2015/W32TeX) (rev 5274) \write18 enabled. system > callbacks > not registering frozen 'find_format_file' open source > 1 > 1 > c:/Ctx-Beta/tex/texmf-context/tex/context/base/cont-yes.mkiv ConTeXt ver: 2015.07.07 21:43 MKIV beta fmt: 2015.7.9 int: english/english ... c:/Ctx-Beta/tex/texmf-context/tex/context/base/strc-ref.lua:1610: attempt to index field 'structure' (a nil value) stack traceback: c:/Ctx-Beta/tex/texmf-context/tex/context/base/strc-ref.lua:1610: in function 'identify_inner_or_outer' c:/Ctx-Beta/tex/texmf-context/tex/context/base/strc-ref.lua:1785: in function 'identify' c:/Ctx-Beta/tex/texmf-context/tex/context/base/strc-ref.lua:1806: in function 'action1' [string "..."]:21: in function <[string "..."]:20> (...tail calls...) ... 45 >> Hello \in{kap.}[NonExisting] ...
