Thank you all for your answers and suggestions, and for the welcome! I checked the things that were suggested, and still seems that the winder is broken. I see that the sidewinder on Amazon boasts free returns, so I'm going to try it. Come to think of it, this machine's winder has been giving me trouble on and off for a while. And on the Amazon page for this machine (Brother CS 6000i) a lot of people said their winder broke. Thanks everyone!
