Sometimes you may want to block a certain activation code if it is compromised — stolen or used illegally.

To block an activation code, click the Block item in the function menu. This will block the code. Any activation attempts using this activation code will automatically fail. The blocked state of the activation code is indicated with a lock icon.

Whenever you want to unblock the code, click the Unblock item.
