This error is coming directly from eBay, not CrazyLister. When you start selling on eBay, you need to select an automatic payment method for your selling fees and eBay is requiring the credit card information.

Please log into your eBay account and add an automatic payment method for your eBay selling fees.

Addition information can be found on eBay's help pages:
Setting up automatic payments

If you have any more questions, you can search our Help Center or, click on the chat tool in the bottom right corner and we'll be happy to help!
