Hello Alastair,
Thank you for your question about the upgrade. Unfortunately the card did not go through, however, because we just changed the credit card service. If you try again, it should work.
We added a couple of premium snipes so that you will not have any downtime, in case this happens again. Please let us know if it does.
If you have any other questions, or require other assistance, we are happy to help.
