"Invalid MerchantID/RegKey combination" Error

[franharrington]

Hello,

We recently got a lot of transactions declined with "Invalid MerchantID/RegKey combination" as the status detail. I am not sure what would have caused this.

We need this resolved as soon as possible so we can begin receiving donations again.

How do we go about fixing this?
