Campaign status: Payment Failure

I just noticed that by my campaign status is: Payment Failure. I checked my credit card details and seems to be fine. Can somebody advice me on this?
Kind Regards

In order to fix the problem you will need to log into your seller account and update your card details. Even if they are the same you need to do this.
Once you have entered your card details you need to retry the payment. To do this you click on the Reports tab. When this opens, on the far right you will see Advertising Invoice History. You need to click on this and you will see a large yellow banner at the top of the screen.
Within this banner there is a retry now button. You have to click on this to tell the system to attempt the charge again. If the retry button does not reappear after about 30 minutes then it is most likely that the payment is processing.
