ALL credit card transactions being declined: "Invalid MerchantID/RegKey combination"

[jseamon]

All credit card transactions have been declined for my account starting yesterday in the early afternoon.

The user gets the message: "Sorry, your payment did not go through. Please try again or contact your bank."

In the backend, we see: "Status Detail:Invalid MerchantID/RegKey combination"

What can be done?

A quick response would be appreciated! All of our donations are currently being declined
