Really confused. Getting an Error when checking out.

In sandbox mode, I get this error after confirming order:

There was an error while processing your transaction: The merchant login ID or password is invalid or the account is inactive. (3)
            Order not completed, data is not valid

I am 99% sure if have the correct login & ID for authorize.net. And the account is active.

Is anybody else getting this error in VirtueMart 3?

do you have a sandbox login?

Yes. I have the same user id and key that were used in the production fields. I believe they are supposed to be the same.

I think I have narrowed in on the problem. The credentials I am using are for CyberSource, which owns Authorize.net. I don't know if those credentials can be plugged into the Authorize.net fields in VirtueMart.
