Do you know if the breeder crated her up at night time? Sometimes if that wasn't the case it does take them longer to get used to it. Have you tried treats for going in? I know it is difficult, but you might have to put her in there and leave the house for about 10 minutes and come back, she will she that you are not leaving her for good. She will get the hang of things, she is just a puppy and they are alot of work, but very well worth it!
