I’m getting the same message as you when I try to insert pdf file 
created by context itself


%%%% begin example
\starttext

\startbuffer
Can this file be loaded?
\stopbuffer

\typesetbuffer[scale=500]

\stoptext
%%%% end example


or when I try to insert cow.pdf


%%%% begin example
\setupexternalfigure[location=default]

\starttext
\externalfigure[cow]
\stoptext
%%%% end example
