Hi again,

Unfortunately the problem seems to come from the junction
of XeTeX + ConTeXt... Indeed the following minimal example

%% begin dalyoung.tex
\setupcolors[state=start]
\starttext
\startMPcode
     fill fullcircle scaled 3cm withcolor red;
     fill fullcircle scaled 3cm shifted (2cm,1cm) withcolor
	transparent(1,0.5,green);
\stopMPcode
\stoptext
%% end dalyoung.tex

works fine with ConTeXt alone, but generates an error while typeset 
with XeConTeXt.
If a file named dalyoung.tuo is present then XeConTeXt stops at the 
line where \starttext is present. Otherwise I get the same error 
message as Dalyoung Jeong, that is
%% begin error message

?
%% end error message

I hope that this would help to locate the error (or a bug).
Best regards: OK
