Hello Rose,
If the winder has seized and will not move you will need to put a few drops of WD40 on the top of the spindleand let it run down and leave it overnight, if you have an electric drill put it over the top of the spindle and tighten the drill up hand tight then switch the drill on slowly if you can, once you have the spindle turning, stop, put a few more drops of WD40 on the spindle and do the same again, once it is moving freely you should be okay, if it is a case of the winder turning then suddenly stopping it may be the winder rubber worn down one end which means taking the body apart to get to it.
