[NTG-context] Buggy source code--> references disappears when I put sections and If I put subjects, \completecontent has void list.

Hi, I'm desesperated. I have I source code (that I attached) that when I substitute any (for example the last) ocurrence of subject for section, then references appears in blank. If I maintain the subjects (and subsubjects...), then \completecontent gives me a void list. What happens?. Hans can you help me?. The last time you help me find me a trouble in my sources (redefine registers). Is this a buggy source....? Thanks in advance, Xan. PS: Yes, I know the source is big, but the error is simpl.
