I enter my serial/license key that I use to register the serial, and the following messages are given to me.
I can only see the message that says it's contacting the activation server, not what happens afterwards.
Entering my e-mail address results in a "customer not found" message.
This is normal. Our software doesn't support direct activation through email, and nowhere we said it does. We always instruct to insert your activation key, and nothing else, and that's the only one that works.
In any case, continuing on this forum is useless, because we would have to share private details about your order. I replied to you at first, because it seems you were able to activate normally, but the activation simply didn't stay.
Now, it seems you are no longer able to activate so, it's best if we continue this by email, so we can check your keys, your orders, etc.
