Norton Utilities question

I had bought the Norton internet security plus norton utilities.

 

So I bought them both together in the same package, but I bought them online. So I have a product code for my Internet Security but not the Utilities. And it work for 2 months, and is now asking for an activation code.

 

Why is it all of a sudden asking for the code when I just bought it, had it installed, was using it.

 

I am rather confused. If there needs to be more details please ask.
