Hi, I am trying to make use of the "hvdm-exm" module for a series of tests and that fails. Below is the basic code I am using. As I could not find a usage sample, I might have it wrong. It fails with \startexam as "undefined" and an internal message that it seems to have a language problem (WARNING ? unknown -- current language en tried). Looking into the file hvdm-exm.tex I can find the source of the error message, but it's beyond me to really understand what's going on. My ConTeXt is updated as of today (30.4.2012). I updated the core file "hvdm-exm.tex" to the 2010-11-17 version but that has no obvious influence. Also checked permissions (just to be sure, folders 755, files 644) and fixed them with no impact. Afterall, the files are all loaded. http://archive.contextgarden.net/message/20101212.154453.528d5fd7.en.html Help would be much appreciated.
