I have bought a student licence and downloaded and installed everything, so far so good. but when a open the programs it says that I have a trial verison, so a try to verify my licens whith my Adobe ID but the it says there is no licence conectet to my ID. Money has been tranferd so there should defenitly be valid licence. I have logged of and in again on my creative cloude app but nothing seems to activate, it's still noted as 30-day trial verisions.
if you purchased your product from these firms like Amazon, you "only" get a redemption-code with which you can request a serial number from Adobe. Please have a look at https://helpx.adobe.com/x-productkb/global/find-your-serial-number.html >>> (Start here: Prepaid card, product box, reseller)
The following part, so I just see at least, ceased to exist on my Adobe website, everything takes place in the link from above. I leave it as an info yet, it might still fit for you. For this purpose, please click your way through to your Adobe Store and find the button "Get Serial Number". Fill in the form and after a while you will get the real serial number.
... in addition:
you should have a look at Adobe's database, to see what's stored/saved about your accounts. Here you will find general infos about your Adobe Account
https://accounts.adobe.com/>>> see My productsView all >>> These registered products are associated with your Adobe ID. >>> Name >>> Serial number.
