NIS 2010 60 Day Trial upgrade to NIS 2011?

I have NIS 2010 which came with my purchase of new computer and it has 60 day subscription.

I tried to upgrade to NIS 2011 but it's not letting me do it because they so call this 'trial'.

Is this suppose to be like this? It isn't those trial software where I got from internet that has 15 days.
