Hi Patrick and Mojca, Something is wrong at live.contextgarden.net. A simple, hello world document fails to compile with luatex. I get bodyfont : 12pt rm is loaded define font | font with name lmroman12-regular is not found define font | unknown font lmroman12-regular, loading aborted ! Font \*12ptrmtfrm*:=file:lmroman12-regular*default not loadable: metric data not found or bad. <to be read again> \relax \xxdododefinefont ...tspec {#4}\newfontidentifier \let \localrelativefontsiz... \fontstrategy ...ame #1\csname #2#3#4#5\endcsname \tryingfontfalse \fi <inserted text> ...yle \fontalternative \fontsize \fi \iftryingfont \fontstr... \synchronizefont ...strategy \the \fontstrategies \relax \fi \ifskipfontchar... <argument> \getvalue {\@style@ \fontstyle } \edef \fontstyle {\fontstyle }\if... ... l.1 % output=luatex engine=luatex Maybe you need to run mtxrun --script font --reload?
