Downloading NIS 2011 for additional PCs

Hi

I have NIS 2011 for 3 pcs.  I only had a desk top before recently purchasing a laptop which has a NIS 60 day trial pre-loaded.

I followed the FAQ "How do I get my product on a new computer" / "Iwant to download my Norton product on ther computers"

Step 1 did not work as there is no 'Download' button showing.

Step 2 - tried downloading NIS 2011 but was was not asked for Product key nor was the Download manager installed on desktop.

Checked current subscription and still says 2 activations available and laptop still has 56 days left on trial.

Can anyone suggest where I am going wrong please?
