To enter the ADM unlocks, log into the ADM client, if the unlocks have already expired and the grace period is up then the unlock window will immediately be presented.
Otherwise after having logged in:
In the top left, click the ADM icon.
Select About.
On the Registration Tab, click Change.
Enter the new unlocks.
If using hosted ADM otherwise known as Workspace Document, login with an email address and the URL for the server is https://document.accessacloud.com then there is no need to worry about entering unlocks, as this is done centrally.
