New machine initializing it rejected it

Greetings,

I've had Storyline on my home machine and a laptop.  The desktop

home machine crashed and I just purchased a new Dell.  I was loading

Storyline last night and punched in the Serial number but it identified the

new machine uniquely and then wouldn't let me initialize it.  I sent off

what they requested but still haven't gotten an initialization thing going.
Just curious what I should do when I go home tonight to finish initializing

Storyline on the new machine? 

Thanks
