contacts missing after update

I have just installed the recommended update which came as a pop up msg. This involved re-installing eM Client(? I think). I must have missed pressing a button somewhere along the way as I no longer have any contacts in my contacts file?? Can anyone help please?

Hello Dave,
if you accidentally upgraded to version 7 of eM Clienta and are missing any v6 data, go to File>Import and choose to Import from version 6.

Regards,
Olivia
