PayPal Express Error: "Your are not signed up to accept payment for digitally delivery goods."

We receive and error message when trying to make a payment on a form. The same for worked well at the end of August but does not work now. The error message we receive is attached below.

I have verified that all the API information is correct.

What needs to happen to get this fixed?
