L_ERRORCODE0 - 10501: This transaction cannot be processed d

Hi,
I know you don't develop VirtuMart, but I was wondering if anybody at the support had this question before.

To process my clients credit card, I purchased at extension "PayPal Payments Pro 3D Secure" at http://extensions.virtuemart.net


I set the paypal account, got the correct API provided by Paypal, but when I try to process the credit card, I get this error.

L_ERRORCODE0 - 10501: This transaction cannot be processed due to an invalid merchant configuration.


The answer I got from StackOverflow is that I would need to have a PaypalPro account.

I purchased this product "PayPal Payments Pro 3D Secure" to avoid to pay for a paypal pro account.

1. What this error means?
2. How do i solve it?

Thanks


p.s: I also contacted the support who develop this extension, but they are not really good.

Hi,
if developer of that extenstion didn't helped you , you do not have choice,
ask PayPal to refund, and purchase plugin from other developer.

We do not help in such a cases, we cannot. Crappy software is not out fault.

Hi Oscar,
yes I know it's not your fault, I was just wondering if had seen that before.

Also, when you develop a virtue store, do you have an extension in mind to use?

Since now, never before
VM3 - really, I saw so many weird cases on that software, so personally since 2 years I do not use nor advise.
