NIS 2010 renewal vs. a new install

Presently I'm running NIS 2010 after removing trial version from a new PC.

Just got off the phone with customer support requesting a reset of my product key which went OK.

He stated that I should do a new install of NIS 2010 rather than renew my subscription (about 100 days left) for the same price once it expires.

Also he mentioned something about it having 5 licenses, 2 of which were added due to so many people having problems with resets.

Anyone heard of this before?
