Question about product key & Norton account

So recently I purchased a 1 year 3 pc NIS 2012 subscription.  I installed the key on my pc.  Then I installed on a netbook which all went fine.  Then I went to check my Norton account and it tells me I have 1 Licensed Installs with No Available Installs.  I should have 1 left so I thought? 

 

 

When I installed on the netbook I used the same key I used on my pc.  On the pc I logged into my account on the program itself, and I didnt on the netbook.  Is that going to be a problem?  Thanks
