I can’t Access my old email account.

Please help me. When I try to sign in on my old hotmail account, it says the account doesn't exist, and since I haven't open my account for quite awhile now, I decided to sign-up again using the old account name. When I want to sign-up the new account, it won't let me create a new account with the email ends as @hotmail.com.  I really need my old email account back as I have register quite a number of website for purchasing (football tickets and movie tickets) using this email address  (*** Email address is removed for privacy ***).
