I have been sent a new activation key where do I fill it in?
Menu > Help > License.
If there is already a license activated, you first need to click on deactivate.
how and where is that done?
In eM Client go to Menu > Help > License and click on the activate button and paste in your key.
If there is already a license activated, click on the deactivate button first.
Oh, that is what I said above. You havin’ a laugh?
