You DO NOT want to 'upgrade' to the latest Pro version... Or the basic version.
Please read around these forums to see the huge problems that people are having with the updates and fresh installs !
Further, the license was only good for six months (maybe a year if you purchased the extended deal, I can't remember) so there is nothing for you to 'update' in a commercial sense.
Beware... You have been warned re: the so-called update !
