Cant use anything in clean up

i bought avast clean up premium, installed it.
It tells me i have som junk to clean up, when I try to do so it tells me to purchase another copy to be abel to clean up the junk.
What did I bye? is it just for telling me I have junk to clean up and inactivating programs??? I can do that without the avast clean up premium.

Have you applied the activation code ?
