It won't let my upgrade or buy a power pack with credit/debit card. Keeps saying error.

Hello James,
Thank you for your question about your payment. I don't think this payment registered. I think our system sent it for $0. I gave some temporary credit until you can try again. It should work now.
You should be good to go, but if this hasn't been resolved to your satisfaction, please respond and we can take the next step.
