I'm using Photoshop CS3, in which it's very easy to turn on the layers.
I don't know what program you're using...
normally, just flight gives you a product number!
You can login to the CS website using this number, how to do that is explained somewhere on this forum.
I know I read it here, but since I don't have to use it myself, I can't remember exactly how it's done.
You should look a little yourself... but you certainly can login to CS with a boxed version.
