It should probably be cs, not cz.
I'm getting the same error message even with "cs".
As I said: my comment was unrelated to your problem.
Isn't "cz" country code and "cs" language code?
BTW: What is the difference what the COUNTRY code and the LANGUAGE code affects?
If you were a citizen of Austria or Switzerlad, you would not be able to use \mainlanguage[at] or \mainlanguage[ch] You need to use [de] instead (which happens to be the same as country code for Germany, but that is just "a coincidence"). Country codes usually have no meaning to ConTeXt. In the case of Czech it is just for the sake of backward-compatibility that cz works. Mojca
