Broadcast import feature has stopped working

Hi,
We have been successfully using the broadcast import feature to publish email newsletters onto our site after sending them out with CK.
Haven’t done a newsletter for a few weeks and then did a couple last week but they are failing to import.
I turned on debugging in the plugin and found the error – the plugin is reporting a problem inserting the post into the database.
I did submit a help ticket to CK from within my logged in client area but haven’t heard back.
Here is the API debug out put to help diagnose the problem.
What additional info or access do you need?
