Problems with KReporter Scheduled Reports

Hey everyone, I am trying to setup scheduled reports in Kreporter, while the scheduled job runs fine, I cannot get any emails received. When I check the log I see lots of:

I am getting SuiteCRM scheduled reports running fine, and I can send workflow emails to both of the emails that it says above are failing. The timing of the SMTP->ERROR messages leads me to believe it is emanating from the 10-minute cycle on the schedule KReport that I have setup to test. Anybody had the same issues please?

KReporter is a proprietary extension not supported by the project. You should contact the vendors. I believe they have a facebook page.

The issue is, the scheduled job runs, but nothing arrives and I see the following errors at the time of the report:

They have replied and said that if the scheduler is firing then the job is running and potentially there is a problem with the way the SugarPHPMailer has been implemented.
