Restore Windows Mail from OneCare Backup/Restore

My hard disk was recently re-imaged as part of a laptop repair. I had backed up my files using Windoes Live OneCare. I then did a restore using Windows Live OneCare. I then tried to Import the restored Mail file, it seemed to work, but when I looked, my old messages were not there. The Imported file structure was there, but no messages. Can any one help me restore my old messages?

Thanks
