Backups Aren't - EaseUS

When I wrote accountancy software the customer manger would walk past with a shoebox full of floppy disks saying "Backups aren't". So I buy EaseUS Todo Backup Home, and it says my license code is invalid. Good job I just have a picture of a cat to backup, or I would be upset.

I got it to sort of work with a 1-month free license code. I still can't believe it is a commercial product.
