zbadkirk,
Hal 6 is a relatively recent release and is far better than the previous Hal 5. Unfortunately, the documentation regarding brain files, help files, etc., haven't yet been released.
What you have downloaded is the Brain Editor for Hal 5 like snicolaou mentioned. It will not work or rather is not applicable for use with Hal 6.
New documentation should be out soon. Stay tuned....!
