My parents wrongly claimed me as dependent? Tax year 2013

My parents claimed me as a dependent for their taxes in the year 2013. I am a 21 years old and not in school. I lived with them January 2013 but have since lived on my own in another state and they have provided me with no financial support except for paying for my health insurance through my father's employer's program. I do not believe I qualify as a dependent and therefor e-filed my taxes which were rejected because my parent's filed theirs fist. What are my options now? I believe my father has knowingly claimed me as a dependent wrongly but do not want cause any criminal action or auditing to come about. What are my options?
