Why did I receive a message stating  The key is already used appears when I try to activate Premium ?

This happens when trying to use a key that has already been activated. License keys can be activated one time only, and will be linked to the email address used to access the Sophos Home Dashboard when the activation took place.
Since the key is in use by another account, you may need to re-protect the current computer using that other (Premium) account.  

How do I fix this? 

There are 2 options to fix this, please follow the one that applies best to your case: 

Option 1 - [Requires re-installation]
Log in to your existing Premium activated account
Re-protect your computers via that dashboard (See How to reinstall Sophos Home  )
To protect additional computers (up to 10) with your Premium subscription follow the "Activating additional computers with your Premium account" section above. 

Option 2 - If you want to swap the Premium subscription to another Sophos Home account, please contact Sophos Home support for assistance.  

Why did I receive a message stating that the email is already in use?

This message indicates that the email address is already in use with another Sophos Home account.

There are 2 options to address this, follow the one that applies best to your case: 
Option 1 - [Requires re-installation] Log into your existing account , switch it to Premium with your key and re-protect your computers via that dashboard. See How to reinstall Sophos Home

Option 2- Create a new account using a different email address to keep using the current dashboard you are logged in to. Keep in mind you will need to use this new account to protect systems moving forward (See Activating additional computers with your Premium account section).
