Email recovery not possible because security info has been changed

My hotmail account has been hacked and all of the security info has been changed. I have used this account for a long time mainly as a secondary email account so I rarely send email from it and i receive considerable amounts of SPAM emails and advertisements so the retrieval questions are virtually worthless to me.  I have had this account for around 10+ years so i have fallen behind on updating the security info but i reallym need to get access back or i will lose several important emails from the past.
