I'm sorry this has happened to you. Have you tried writing her a letter telling her how her silence makes you feel and that you love and care about her. Remind her that you would not intentionally upset her and if she tells you what she feels you have done you will be able to understand why she is so upset. Ultimately I would also tell her that if she chooses not to reply to your letter you will respect her wishes and not make contact with her again.
Unfortunately you cannot force her to tell you what is wrong but ultimately as she gets older she is going to learn that everyone makes unintentional mistakes and that second chances and sometimes 3rd and 4th chances are something we humans can do open heartedly especially if we can see that the mistake was not intentional in the first place.
