Nowhere to enter renewal code

I purchased Norton Internet Security 2010 a while ago after my free trial ended. When I opened my Norton product, I did not see the button in the corner that said "express renewal". This was a while ago, so I can't remember what exactly I did, but I think I got another free trial of Internet Security 2010 to protect my computer while I tried to figure everything out. Now when I open my Norton product, I see this

Not this

And when I click on "activate now" I see this

But my renwal code doesn't work, as I'd expect.

 

I want to know if there is a way where I can get the screen to appear where I can enter my renewal code (will downloading a trial work?) or can Norton give me a product key to use instead?

 

I have Internet Explorer if that makes a difference, and I am signed up to use my Internet Security on 3 PCs.
