Hi Azure11, if the cord keeps breaking you may be loading it wrong. I've had this happen. I can't explain how to wind the string on because I don't know what type of machine you are using. If the cord is tangled or knotted while loading, this could cause it to break. And if you use a string that is too thick for the machine, this could cause it to break also. If you don't have a manual, you may have to go back to the place you bought it, or a place that sells that machine and ask for some help to load. Also if you lose the spring that pops out when you are loading, this could cause it to break. Or if you wind the string on clockwise, when it's supposed to be counter clockwise (or vise versa) it would break or get jammed. Good luck with that.
