Payment problem

 After summerbreak, i would like to activate my account again. In the meanwhile, i’ve got a different creditcard and filled in this information. After the acceptation of the following text ‘I hereby acknowledge that my Zwift membership will auto renew every month until I cancel. See full terms.’ the following note is comming up:"Subscription ErrorThere is an issue with your payment. Please
re-enter your details and try again’. 

What is going wrong and how can i activate my account. My creditcard is valid and I write down the correct number.

Kind regards.

I have the same problem with paypal
