Message "Your Demo License has expired"

I have a license for the the eM Client that includes lifelong upgrades. After using it for years, now I get a message “Your Demo period has expired”, and I am asked to buy a new license. Can we clarify that?

Many thanks

You need to activate your Pro license, which you can do by going to Menu > Help > License and clicking on the Activate button. Then pasting in your license key.

If you have lost the activation key, you can have it resent to you by entering your registered email address here: Lost Activation Key | eM Client

Thanks for the quick reply - that works.
