I recieve a message from Adobe that there is a problem with my payment for Acrobat Pro DC. Dont understand, because I checked the card number and bankaccount and this is ok. Maybe it is because I use Acrobat Pro Dc on a new computer. But I don't understand why this leads to a paymentproblem and I don't know how to solve this.
Using Acrobat on a different computer is standard operation and does not affect your payment.
You could look into https://account.adobe.com if there is a real problem with a payment. The message, if given by mail, could also be scam to get your credit card information.
Payment problems are only happening between the Adobe payment system and your card providers payment system. So you should contact your bank to see what is the problem. If they say that there is no problem contact Adobe customer care: Adobe customer care can be contacted here: https://helpx.adobe.com/contact.html - click the small callout at the lower right of the screen and type "agent".
