Free Credit Score Not Working

All of my information is 100% correct, including my SSN, yet every time I check the "OK, show me my free credit score and report." it says "It looks like some of your personal info isn’t correct." It then tells my to enter my 9 digit SSN. My SSN is 100% accurate and I have entered it in over 10 times now. Why isn't it working? This is incredibly frustrating.
