If the activation cannot be validated

Define what the application should do if the online validation fails:

Exit the application

Blacklist activation key: this causes the activation key to expire. End users are prompted to enter a new activation key. This can be the previous one: if the user enters the same activation key as before, validation is required again.

Do nothing. Use the VBA extension feature of XLS Padlock to retrieve the state of validation: refer to the demo VBA code available.
