This is the first time I have posted here. If this question has already been asked, I apologize. I bought the Memorex Express It Label Maker kit that included a round plastic labeler. There weren't any instructions for that--just software instructions on how to make the labels and a cd to put their software on my computer. I'm not having any trouble at all making the labels for my CDs and DVDs, but I am totally clueless as to how that round thing is supposed to help me get the labels on the discs straight...it pushes down in the center and locks--what does that do? It says on the box that the little plastic hook things in the center will keep the labels from curling? Could someone please tell me how to put my labels on using this thing? Thanks so much.
