Cannot install Norton after accidental uninstall

When I built my new PC last Black Friday the Windows I got came with Norton for a month, after that month I bought it. Now I was going through my programs in my PC looking for bad things and I deleted a lot, but I accidentally removed Norton, don't ask I know there is a lot of protection, I wasn't thinking. Now I have Identity Safe and the three website toolbars, but I can't get the actual Norton Security back on my PC. It says "Download Norton" under "Add a new device" but other than that I can't find anything that will help me. Here are some screen shots.

With the top one, I don't understand what happened there, I never really went on the website for everything since recently, 3/3/2014 seems to about the time I bought Norton, but I can't find the e-mail from when I purchased it, and the other "Norton Security" (did not post, has key) where it says it's expired, I know I have like almost 100 days if I ordered it on 3/32014. Also, what does the "1 of 3 seats used" mean? I have a lot of problems please help!
