Try trunning
makempx -tex=latex 2MS6.mp
directly. Maybe that gives a better error message

Best, Taco
   
  

This is what I got:
   
  C:\Han\slide>makempx -tex=latex 2MS6.mp
makempx: Need exactly two file arguments.
Try `makempx --help' for more information.

  C:\Han\slide>makempx --help
Usage: makempx [-tex[=<program>]|-troff[=<program>]] MPFILE MPXFILE.
  If MPXFILE is older than MPFILE, translate the labels from the MetaPost
  input file MPFILE to low-level commands in MPXFILE, by running
    mpto -tex, tex, and dvitomp
  by default; or, if -troff is specified,
    mpto -troff, gsoelim | geqn -Tps -d$$ | gtroff -Tps, and dmp.
    The current directory is used for writing temporary files.  Errors are
  left in mpxerr.{tex,log,dvi}.
    If the file named in $MPTEXPRE (mptexpre.tex by default) exists, it is
  prepended to the output in tex mode.
  
 
  There is one file called "mpxerr.tex" which contains stuffs like
   
  \mpxshipout% line 156 2MS3.mp
$A$\stopmpxshipout
\mpxshipout% line 157 2MS3.mp
$B$\stopmpxshipout
\mpxshipout% line 158 2MS3.mp
$C$\stopmpxshipout
\mpxshipout% line 159 2MS3.mp
   
   
  Does this mean anything?
   
  
Thanks,
  Steve
