I hope you can get the tracks that you need, get the machine set up and get back to what you wanted to do in the first place. As a general rule, I've always been one to "stand up" and wouldn't let anyone get away with something like this...but I tell ya'...with the crazy world, her knowing where you live and knowing that you live alone....I probably wouldn't mess with her..who knows..she could be really dangerous..not worth the chance to me. Just get what you need and stay safe...hard lesson unfortunately learned. I'm sending you hugs...wish I was closer..I'd come help you put it together and figure out how to get it up and running.
