PayPal Payments Pro extension throwing error

[Sam_78]

Hi I want to use PayPal Payments Pro extension so that all my credit card and Paypal both can be managed at same place. I have inserted my API Credentials  and tested it. 
I see "Connection is successful and API Credentials are configured correctly.  " now when I go to cart and try to make a payment via credit card I get this error " This transaction cannot be processed. The merchant's account is not able to process transactions."

extension version 1.0.2
AbanteCart version 1.2.12

I used authorize.net extension but now I want to use paypal pro and get rid of authorize.net

Have you considered using PayPal Standard or PayPal Express -  both accept credit cards.   And they don't have the $30 monthly fee that PayPal Pro does.
