Outlook express address book

The address book in Outlook Express on our desk-top won't show addresses. They are still stored, and we can find them by searching when we write a new e-mail, but when we open the address book, it just shows a blank page!
This problem just happened one day when I had been deleting some old entries, and so it's possible somehow by clicking a combination of buttons that I've told it to hide the address book. Any ideas how to get it back in view? we've tried everything we know:

The simple solution would be to try a system restore to a time before the problem occurred.

Or you could try this program

I have not tried it but it may help your situation.
