Putting many command and setup in the before and after keys for \definestartstop
isn’t the nicest way to create start/stop command, Hans used a two step method
and put all setups and separate commands which are now used by \definestartstop.
Defining command with \unexpanded\def\…{…} instead of \def\…{…} can prevent
you from unwanted side effects when you use command in headings etc.

The information you provided aren sufficient to reproduce the error,
according to the message there is a problem with columnsets but there
is no way to tell why you get it.

Can you provide a working minimal example which does produce the error.

There is no difference between \define and \def in MkII but for MkIV
there is a difference because \define is \unexpanded\def and the new
command \defineexpandable corresponds to the normal \def.
