Hi Reiner,
I started with the 4.0-version myself as well, back in 1990 (?).
I bought this product overhere in the Netherlands at a company
called 'Personal Software Design' (what's in a name, ehh ??).
They informed me about new releases/updates etc.. I had
to BUY version 5 (upgrade-price, about $100,-- (????) and
lateron I had to BUY version 6 too (upgrade-price, again
about $100,-- (????)). As you can see, I don't remember
the upgrade-price, but that's why somebody invented the
telephone  :-)
If you are going to make this call, be sure to have the
registration-number written down on a piece of paper :
Start your 4.0-version and press Ctrl-F1 : this will display
your registration number.
Any time !
Regards,
Arjan, the Netherlands
