Dear All, I still have a large problem with the newest context update which is incompatible with the latest MikTeX installation. Many files are not regularly processed anymore. Does anybody have any suggestions as to how to clean up the right Context files and reinstall an older version? I prefer not to make a mess of my Miktex installation. Latex still works. Thanks in advance, Robert This is pdfeTeX, Version 3.141592-1.30.6-2.2 (MiKTeX 2.5) (preloaded format=cont-en 2007.3.4) 9 MAR 2007 18:00 entering extended mode **facturen.tex \emergencyend (facturen.tex ConTeXt ver: 2006.12.20 23:52 MK II fmt: 2007.3.4 int: english/english language : language en is active system : cont-new loaded ("D:\Documents and Settings\All Users\Application Data\MiKTeX\2.5\tex\context\b ase\cont-new.tex" FatalError : Your format does not match the base files!
