Sorry, my fault but it does not solve the problem. I obtain the 
same error with fresh context and corrected version of this file:
-----------------------------------------
\startenvironment ma-cb-env-cz
\mainlanguage[cz]
\language[en]
\enableregime[latin2]
\stopenvironment
-----------------------------------------
There is something wrong with ma-cb environment files. The file 
ma-cb-en does not compile. I get an error
! Undefined control sequence.

I tried making minimal example of the file that you posted, but 
always get the same error. I am pretty certain that ma-cb-en.tex 
used to compile in the past.

Hi Aditya,
I had the same problems in past in solved them by myself. The problems
are dutch commands in the style-files and a typo.
I attached my corrected style-files, because it is faster to replace
send you the files than I need to look where I made corrections.
The files did not correct the problem with the backgrounds in the
headers Vit has mentioned.   
        \edef\StatusAchtergrond
          {StatusAchtergrond%
           \ifodd\realpageno R\else\ifdoublesided L\else R\fi\fi}%
\ifdubbelzijdig -> \ifdoublesided
this low level if has been changed, ad a result tex's 'fast if then 
else ' skip routine does not see the \ifdubbelzijdig is if and gets 
confused
Hans 
Great, thank you Hans!
Let us process to teh next two problems also visible in the test file.
1. In the chapter ornament (a gray spiral with red dots) the red dots 
are not dots but lines.

Great Hans, it works well! Thank you
