This error is coming directly from eBay, not CrazyLister:
"You must accept the terms and conditions for automatic payment method that will be used to pay any charges related to selling and buyer reimbursements. Once you complete the above step, you will not be asked again on your other listings."
What needs to be done?
Simply CLICK HERE and accept eBay's terms and conditions agreement.
Once you've done that, simply "Sync from eBay" on your CrazyLister account and you should be good to go :)
