In case the license was locked (either because of a license transfer or because of a manual license revoke on the Activation Server 4), the user has 3 options

 

 

Free a license by making a license transfer on another computer (only possible if the license was locked because a license transfer was made on this computer)
Try to activate again with the same Serial Number. This would only work if the license lock is removed on the Activation Server 4
Activate with a new Serial Number
