Either they haven't understood what you need or they looked into different account. Do you have sandbox account? DPRP(Direct Payment Recurring Payments ) is separate service that should be enabled in your account which allow to accept CC recurring payments. There is no other solutions for this error message. DPRP must be enabled for your paypal account and you have to contact paypal and ask to enable it. If they still claims that it is enabled, contact them provide full transaction log and ask to explain why this error was generated then?
