I have just open a QB Merchant Account. I've installed QBMS v1.8 on Zen Cart 1.3.8a

I've been through the whole PDF that came with QBMS 1.8 and have created the App ID, App Login and connection ticket. My settings are:

Enable - True
Desktop
AppID
App Login
Connection Ticket
SSl Cert - blank
Testing - False
Verify with CVV2 - True
Sort order - 1
Payment Zone - none
Set order status - Processing
IP address - blank

When I do a test transaction and click on confrim order I get the following error message An error has occurred within our system while trying to process your credit card. Please try this transaction again. If the problem persists, please email [email protected] to place your order.

If I change Testing to True then the order goes through fine, I get e-mails confriming the order but there is nothing added to my Merchant Account.

Any ideas or help would be appreciated. Thanks.
