e-mail address or card number that belongs to an existing PayPal account
You cannot use an e-mail address or card number that belongs to an existing PayPal account. If you have a PayPal account, please log in. If you don't, please change the e-mail address or card number and try again.
I've tried 3 different things just trying to pay with my credit card-------
付款时出现上面问题的原因是:
1地址或者信用卡用在其他PAYPAL账户了,(That error message only comes up when the card or email has been used on another PayPal account.)
2信用卡或者邮件被回收了,或者信用卡被其他人注册了(It may be that your card/email are recycled or it may be that something else you registered for created an account for you. )
3卡被朋友或者家里人关联了.The card may also be linked to someone elses PayPal account, like a friend or family member who helped you make a purchase in the past.
