Q: My Contacts used to sync with Outlook. As of today, all of my contacts are gone. What do I need to do to sync with Outlook 2011?

I have a Macbook air with OS X version 10.8.5.  I am running Microsoft Outlook 2011 Version 14.3.9.  I use SyncMate to sync my Android phone with my Outlook Contacts.  It uses the Mac Address Book as a go-between.  Today I synced my phone and all of my contacts were deleted from the phone.  I went to my Mac Address Book to find it empty, all 843 contacts gone.  Fortunately my contacts are still in Outlook.  I need to know how to get them to show up in Address Book again and to sync automatically with Outlook.  Please help!
