The error message you're getting actually comes from the uc_recurring module. It's not saving your recurring fee - I think the only reason this will happen is because it's using the wrong recurring fee handler for your payment method. Have you selected uc_cim as your recurring fee handler (admin/store/settings/products/edit/features)...
That did it. Thanks!
If I leave the Number of billing periods blank do you know if it keep taking the payment indefinitely.
