Hi, In these two months, Eset Endpoint Security (EES) 6.6 became deactivated suddently. Then it showed Product not activated in red; and prompted for Activate with license key. Before that, it was activated well. This situation mostly happens when the PC was cloned from the image in which EES 6.6 was already activated with key. Normally, it would be activated again having the license key in. Any idea or help. Many thanks, Bruce
