Live Email Address Accidently Deleted

I gave one of my old computers to my daughter and I guess my Microsoft Account ( email address ) was still linked to that computer.  My son-in-law wanted to change the computer to logon to his own account so he deleted the existing account ( my email address ) and added his own account.

 

Bottom line is he has accidently deleted my live.com  email account and address.   

 

The address he created links to my old account but it won't allow me to open anything ?  I suspect that might be because my current computer still

boots to the account that he deleted ( not the new account he created ) ???

When I go through the support online it either wants me to login ( which I can't with my old address) because he deleted it, and/or if I use the new

address he created and try to change the alias there is no longer a suffix available for live.com, there is only Live.ca, Hotmail.ca, Hotmail.com or Outlook.com

none of which get me to where I need to go to resurrect my old address.  It won't let me type in live.com either.

I have tons of critical info in folders that I need to access.  Is there a way to reset or get back my old live.com address that points to my old account ?

Any advice or direction would be appreciated !
