I get it, that's it.

No, it no longer exists. To activate a third device, you need to create a new account.

Yes, that´s my case, but it seams they applied the new restriction to 2 devices. Is there a way I can go back to Kaspersky Security Cloud package?

@diff There may be 3 devices if the subscription was activated a long time ago with KSC Free.

Correct, that must be the reason.

Apparently you had a license for Kaspersky Security Cloud Free. It did include three devices. This product no longer exists. That's probably why the restrictions have changed.

I see, in my account it reads 3 devices instead of 2. Thanks
