I  do not have an Address Book any longer, however when I start to put in a name in the TO some pop up. How can I access the address book for updating adding and deleting

I've searched the prior questions, and I've seen lots of other Hotmail users having safe email messages (some even from Microsoft) marked as "very suspicious" when the sender is both in the address book and on the safe sender list.  I'm still having this problem even though in some threads here it says this problem has been fixed.  It clearly has not for me.
On new Dell Inspiron 17R laptop with Windows 7  and MS Live mail installed, I am importing files from an old PC running Outlook Express 6 on Win XP.
I have successfully copied the old e-mail files (*.dbx) but cannot find how to import  the Address Book (.wab file) into the Contacts file. Information I find on the web and on Microsoft refers to  "Tools" tab or option which seems to  have disappeared in the latest version.

Please  explain.
