quite some code is being rewritten / adapted to context mkiv so there 
could be low level differences
can you make a small example, since this else problem can come from other 
places than reported
There are demonstrative files. Please, run
  texmfstart texexec --pdf ma-cb-cz-test.tex
and
  texmfstart texexec --pdf --mode=screen ma-cb-cz-test.tex
this file: ma-cb-env-cz.tex refers to itself and probably should be :
\startenvironment ma-cb-env-cz
\environment ma-cb.tex
\mainlanguage[cz]
\language[en]
\enableregime[latin2]
\stopenvironment
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
