MarcinDobry wieczór,

Kiedy instalacja 9 należy także pamiętać, by korzystać z tego samego adresu e-mail, który został użyty do rejestracji 8, więc system rozpoznaje go i pozwala na upgrade.

Daniel, thanks for reply. Let's talk in english, google translate is sometimes unreadable ;)

I checked all e-mails after purchase. And I found my fault.
I was so excited about the new version relase that I made the purchase of an upgrade of Website X5 Compact 9 instead of an upgrade of Website X5 Evolution 8.
How We can fix this? Purchase another license, re-purchase the proper upgrade or purchase Website X5 Compact 9 as the basis for the upgrade is not an option for me...

Hi Marcin,

There is an option from the Compact 9 too :) at this link: https://incomedia.cleverbridge.com/627/?scope=cart&cart=90869&showcart=false&recommendation=edcd

This is the only option for getting the EVO 9 on a lower price, because we cannot change your licence from Compact 9  to Evolution 9 :(

You'll love the EVO 9

Ijustclickedthis link, but my first version was Website X5 v8 evolution.
I want to buy upgrade from  Website X5 v8 Evolution to Website X5 v9 Evolution.
By mistake, I bought upgrade from Website X5 v9 Compact to Website X5 v9 Evolution.
And now, This purchase is totally useless.
Maybe I could pay the difference between the prices and become an owner of an upgrade from v8 Website X5 Evolution Website X5 Evolution v9?

You must registre with your old e-mail, it must be the same as you registred you first Website X5.
