Hi,

1. Try to make shorter example because your example contains too much 
stuff for a minimal example.

2. You forgot \starttext in your example.

3. Your fonts don't contain greek letters which explains the missing 
counter in the PDF. Did you check if the fallback fonts are loaded.

\setuphead
   [section]
   [number=no]

\setuphead
   [subsection]
   [number=yes,
    sectionsegments=subsection,
    conversion=g]

\setupbodyfont[dejavu]

\starttext

\completecontent

\chapter{yay}

\section{wow}

\subsection{Text}

\stoptext

Wolfgang
