Testabo oder nun doch Abo? Ich bin verwirrt

It can be taken up tp 24 hours until a subscription became active.

So take a look tomorrow into ypor account.

Have a look here:

https://helpx.adobe.com/manage-account/kb/stop-creative-cloud-trial-mode-after-purchase.html

your subscription starts and the trial ends as soon as you make your purchase.

start by checking your account to verify your subscription is what you expect and to verify your adobe id, https://accounts.adobe.com

then, if your account shows an active subscription, sign out and then back in to your cc desktop application using the same adobe id used to verify your subscription: http://helpx.adobe.com/creative-cloud/kb/sign-in-out-creative-cloud-desktop-app.html

if your account does not show a subscription, contact the vendor.

p.s. buying from a non-adobe vendor can cause an issue because, if you have a problem, it's often not clear who (adobe or the vendor) is responsible for fixing the problem.
