Hello, I am using the default implementation of TeXLive 2010 which provides MetaPost 1.211 on Windows 7. I'm getting a fatal error on texnum.mp on the simplest possible use of graph. Here is the simplest possible test case that shows the error: input graph end Here is the error message I get. C:\texlive\2010\bin\win32\mpost xtest This is MetaPost, version 1.211 (Web2C 2010) (kpathsea version 6.0.0) (./xtest.mp (c:/TeXLive/2010/texmf-dist/metapost/base/graph.mp (c:/TeXLive/2010/texmf-dist/metapost/base/marith.mp (c:/TeXLive/2010/texmf-dist/metapost/base/string.mp)) (c:/TeXLive/2010/texmf-dist/metapost/base/format.mp (c:/TeXLive/2010/texmf-dist/metapost/base/string.mp) (c:/TeXLive/2010/texmf-dist/metapost/base/texnum.mpfatal: Command failed: etex - -parse-first-line --interaction=nonstopmode mpa05524.tex; see mpxerr.log >> texnum.mp >> texnum.mpx !

Or is there some other debugging I can do to determine how to resolve this problem?
