Thank you for posting, patrickf96215280.
I understand how frustrating it can be when a valid VAT number is not accepted during the billing process.
I reviewed both Adobe accounts associated with your community profile and found no active subscriptions or purchases. I also confirmed that neither account is currently configured for Germany.
If you have a valid German VAT number, then you'll first need to ensure that the Adobe account is set up for Germany. Once the account is configured for Germany, you can review the instructions in the following document to add or update your VAT information:

If you continue to receive an error after the account has been configured for Germany and the VAT number has been entered, please reply with the specific error message, and we'll be happy to take a closer look.
Please update this discussion if you have any additional questions, patrickf96215280. ^JW
