For your first question, no.
I believe the file (ver.6) of Hal IS the full version.
If you purchased Hal 5 just prior to the release of Hal 6,
then you should have been notified and a serial number
was emailed to all purchasers.
If this is not the case for you I'd suggest you email
Robert Medeksza and explain your delima to him otherwise
he might read your posting here and contact you.
