major error msgs near end of eCart wizard

So, so tired of thinking I've made progress with eCart only to get more error msgs. This time the wizard is building the checkout pages and suddenly up pops TWO windows of error messages (see attached).
I notice that the wizard stopped at the "checkout_failure.php" page (it opened a file from the template but added nothing to it.)

What version of Dreamweaver, eCart, and what type of MAC are you using? We can try to reproduce the problem, or we may have to work with you in a private meeting to debug it if we can't reproduce it.

It appears to be a bug, but it isn't very common so I'd like to know a little more about the operating environment so we can try to reproduce and fix the bug on our end.

attached are screen caps that should tell you about my stuff...

I have opened a support incident to help track progress on this issue.

this is not an answer to my problem...

You can update the ticket and we can call you to investigate it further. It will show up in the Support History section of our web site.

This is not a common issue, so we don't know the solution just yet. The incident will give us a location where we can share information privately and schedule phone conversations that will help us get to the bottom of the cause and possible solution.

Much of our QA staff is out on holiday this week and I don't have a mac to reproduce the errors. I'm hoping we can reproduce it internally, which will save your time from having to sit on the phone while we work through the cause.
