Hi everyone,
one addition I forgot to mention in the last update is a new “De-authorise computer” option on the website itself.
If the computer hasn’t updated its license since the renewal date you can immediately deauthorise from the website.
If it has a current license, then it will automatically be deauthorised at your renewal date, or next time it connects to the internet, whichever is the soonest.
If you urgently need an immediate de-authorisation and don’t have access to that computer, you can contact me, but obviously this will be at my discretion 
Full instructions are of course in the manual Authorising and de-authorising | Liberation User Manual
Hope this helps!
Seb
PS sorry for all the email notifications, I’ve been tidying up the categories and didn’t realise it would mark the posts as unread, oops.
