my free trial period expired.I was sent a activation key. How do I use the activation key? Where is inserted?

This is a new computer with the eM client installed. The license
expired. I was sent activation key. The activation key went to my I-pad not to the new computer.
How can make eM client work again.

I have not received any answer to my questions.

I don’t receive any messages.

Hi, you can activate eM Client in Help - License.
