You can have 30 components on the top level. Those components dont have
to be simple models they can be blocks attached to lower level
schematics. These lower level schematics can each have 20 components.
This means that, in principle, you can have 30*20=600 components. No
other commercial demo of a simulator, to my knowledge allows such a
large number of components.

You should have read *all* of the page. There are two main password
options. One is in the vain of Windows XP, i.e. it locks to hardware.
Many Cad packages do this.
The second option is to pay a little more, i.e. $300 verses $225 for the
gold versions, and get a password file that is usable on *any* computer,
but is licensed only for that individual.
