Sorry for the late reply. I will be traveling for the next two weeks, and don't
have the log here. As mentioned, I was in contact with the tech support people,
and should be able to make a temporary account when I get back. As such, a
monitor level trace can be made, and I can share the keys used.

Thank you for your time so far.
