When you use a client without internet connection, there is a problem de-activating your license. 🤔
The client wants to send info to the web to make the license code available again for re-activation, but this will fail.
However, the license is removed. So you are not able to re-activate the license anymore.
There is a nice offline activation, what about a offline de-activation?
