This customer hasn't configured Google Checkout properly which is the source of his frustration. I demonstrated that event registrations work on their system with a different payment method and their only error they are getting is caused by not having SSL enabled on their server. We will get him running and he did a really nice job of setting up his events. We could have been more helpful in correcting his set up. I'd like to keep him as a happy client as he is using some sophisticated features and has become proficient with DT Register.
