Off-line activation differs from on-line only in way you transmit and
get data from our web server. In on-line mode this is done
automatically, in manual (off-line) you should manually copy this from
registration wizard to web page.
Activation count increased each time you get key for _new_ PC. And of
course blocking limit exist, but normally you should not reach this
limit. Please see this ticket for explanation:
