Today I took my 'old' Win7 Home Pro computer and set it up at my daughters house.  I had used Win Live Mail on it.  While setting it up I found some of my old contacts while I assumed were still in some file on that old computer, so deleted them.   Apparently I was deleting something from Windows Live Mail somewhere, because when I came home and signed in on my own personal (home) computer (Win 7 Pro) I had no (zero) contacts.  Have I lost 200+ contacts?  Do they reside somewhere in a file on my home computer, or were they all kept 'at Microsoft'? 

When I was working on her (my 'old') computer., my new computer at my home was not even on, much less connected with Windows Live Mail.  What gives?
