Apply serial number does not work: you have in Amazon at a tiny spot a reference to the licensing by authorization code. If you make it to Adobe, there is passed from pillar to post, always in a circle. The same goes for the telephone hotline, they will not even appear in the imprint is there a number. The evening, however, is not occupied, where one supposedly kannn chat 24h / day with the support. But when calling the chat states: up to 17 clock. Here and there you jump times into English and then into German, sometimes you have to choose a product whose product number, the customer neither Amazon nor receives in the installed trial version is stored as Info. A serial number can not tell you if it has been discovered at least an appropriate validation form (in English for US customers), because it is precisely this to be only just been assigned. Never before have I seen such a loving Chaos: well meant and made schlimmstens!
