Some hardware changes (as upgrade the BIOS, or format the harddisk), can cause a activation lost, this is the normal behavior of the licensing system, you only need to reactivate your license to use the software again. The five activations is only a soft limit, if you exhaust this number or you are close to it, send us an email and we will reset the counter. You can request for more activations any times as you need.
If you plan to update the hardware very frequently and the activation system is a inconvenience for you, we can switch your license to a network-floating type, that only needs to be activated in the server. If you are interested please contact with us to email@example.com.
The activation system is only a way of protect us against piracy, but we don't want to bother our legal users. We only would to raise objections to add more activations, in very obvious situations of abuse of license terms.
