Things like this happen, don't let it discourage you. I remember a time when I was making something for my DD or myself that required buttonholes. Well, my machine has an attachment for that, but I could not get it to work, so I was ready to take it in to the repair shop. My DH looked at the instruction manual (which I also had done), then brought down a lever that I'd not pulled down. Boy did I feel stupid, although at least I didn't have to face the dealer, who probably would have laughed at my mistake. Stuff happens to all of us.
