Hey, glad the refund worked!

For your error, it looks like you're going to (or being taken to) the wrong URL. It should be:

admin/store/orders/[order id]/cim-charge/[cim_ppid]

Without that last part, you'll get that error. I should probably trap that error before it happens. But the question remains, how did you get to that URL? Did you click "(charge)" next to the credit card you wanted to charge? Was that link missing the cim_ppid portion? I can't think of any reason that would happen, other than you're somehow missing that data in your uc_cim_payment_profiles table.
