If you don’t have sufficient authorisations remaining then you can deauthorise one of your older computers.
To deauthorise MixEmergency:
1) Make sure that the computer that you wish to deauthorise is connected to the internet.
2) Launch MixEmergency on that computer.
3) In the menubar, select “MIxEmergency”, then “Authorise…”.
4) On the Authorisation window that opens, push the “Deauthorise” button.
If you no longer have a computer, or are unable to operate it for some reason (e.g. it is broken), then please email me at support@inklen.com from the email address that you used to purchase MixEmergency and I will be able to help you further. 🙂
