Account blocked due to suspicious activity

I'm trying to recover my account after it was blocked because of suspicious activity.  This account is over 12 years old and I no longer remember what the security question was, or what the answer is. I rarely send out emails with this account (I use it for my banking information and for receiving delivery confirmations from online shopping sites, etc) so I have no idea how to come up with enough information for the automated system to allow me to recover my own account. I was hoping there might be another way for me to get into my account, maybe if I could provide enough information about emails I've received in the last month or whatnot. I badly want back my msn messenger as well, which I'm currently unable to access because of my account being blocked. I have no idea if there actually was suspicious activity or if it was because I logged into my account at a different location than my home (though I've been there a few times so it's not a new location), but I've had it for years and years and never had an issue till now. I'm so frustrated; that email account contains so much important information. Is there any way I can give my information and see if someone can help me regain access to my account? I had to create another account just to be able to access the message board to ask for assistance in regaining access to my original account. Thanks!
