em client 6 beta expiring without licence en preventing further usage

Installed the em client 6 beta. But now without licence, software has expired. Software prevents me from sending emails. I’m unable to reverse to em client 5 because installer says that a more recent database is present. I would like to keep all my email history. Can you provide me with a link for a more recent beta version or a definitive em client 6. Feedback appreciated
