This was kind of a goofy set up, as you don't just "get the serial #'s"
I downloaded the ST4 4.1 Update, and own the full version, but didn't
get the CS or even the Edit in my account. Somehow I stumbled upon
a "Pop Up" that said "get ST4 CS and Editor" and, after I clicked on that,
THAT Is when I got the serial #'s added to my account...
So those who don't have Serial #'s kind of putz around on the IK
Site until that Dialog pops up to add them to your account
