Zahlungsprobleme

do you see billing problems on your end, or does your credit card records show you’ve paid?

if everything is fine on your end and your credit card shows you’ve paid, check https://helpx.adobe.com/manage-account/kb/unknown-charge-on-bill.html to make sure you’re checking the correct account when checking your account to see if payment problems are listed there.  if there are payment problems shown there, fix them per https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html

however, if there are no payment problems shown on the billed account nor on your end, follow the ​@Manan Joshi link, https://helpx.adobe.com/manage-account/kb/stop-creative-cloud-trial-mode-after-purchase.html
