downloading new elements

Hi, I have just upgraded to E4 and bought new elements. I am thinking they would be on the USB stick. If so, can someone tell me how I access them, other than writing each of them in manually - my chances of getting them right first up is pretty lean.
Thanking you. Carolyn

Please disregard my previous request. All became clear as I spent time browsing through the E4 program.
Thanks, Carolyn.
