# Expired and Invalid License Keys

Navigation: Working with Nx Witness > Nx Witness Licenses > # Expired and Invalid License Keys |

Under some circumstances, a license may become invalid. For instance, when a server is removed from the System or goes offline, the licenses tied to the hardware ID of that server will become invalid. When the server is back online or reconnected to the System, the licenses will be active again without configuration.

However, if a server change results in a hardware ID update, all licenses tied to the previous hardware ID will become invalid and can only be activated on the new hardware ID by contacting support at support@networkoptix.com. If a hardware change is planned, the best approach is to contact support prior to the update so licenses can be intentionally deactivated before the hardware change, while they are still active and valid, and reactivated once the new hardware ID is established.

Note: A trial license cannot be deactivated nor reactivated once it expires.
