New subscription of NIS2011

My present NIS is a box version of NIS2010, upgraded to NIS2011. I have one remaining activations left because I bought a new computer and installed NIS on it. I had the NIS uninstalled from the old computer and threw out the old computer. When I check my Norton account, it showed one remaining activation.

I recently bought a box version of NIS2011 with 3 licences because my subscription is about to expire. If I renew my subscription with the product key from the box version of NIS2011, will my Norton account show I have 2 remaining activations? If Norton account shows one remaining activation, how do I reclaim the other activation since now I own only one computer and have NIS2011 installed on one computer?
