Norton Internet Security 2012 Not Working or Recognized by Remover Tool

I recently purchased NIS 2012 for my HP desktop after my trial expired in June. I ran a startup repair on the computer and it found and fixed corrupted drivers (this was about a week ago.) Since then, NIS hasn't been coming up when I click on it, my Norton Toolbar has dissappeared, and I am also unable to uninstall it.

 

I downloaded the Remover tool for my product and saved it to my desktop, but when I run it I get an error message saying "Failed to detect any Norton product that could be automatically updated." In case this matters, I downloaded the product from the website (it's not a disc copy) so maybe that's why the error is coming up?

 

Any help is greatly appreciated.
