Cant receive mail so when I checked was asked for activation code. Cant find one as may have deleted it by accident
If you have a Free or Pro License, go to http://www.emclient.com/lost-activation-key and enter the email address you used to register and a copy will be sent to you. You can then go to the web interface for that email address and get the activation key.
If you have a Pro License, you can additionally go to http://www.emclient.com/reset-password and enter your email address. That will reset your password and send your activation keys to your email address.
