Hi

I have been using Windows Live Mail (2009 version) for my emails for about 6 years. My contacts list had all my email contacts from the last 18 years. Two weeks ago my contacts completely disappeared, apart from a random 7 contacts which I don't particularly use. My computer had been running low on memory. There were no updates that I had run at the time. It appears I had not set regular back ups of the contacts (I wasn't aware you could, never had this problem with outlook express). How can I get them all back? I have searched the internet for an answer but no luck so far. Can anyone please help me??? They must still be somewhere in my computer, but where?

Thanks
