Thank you for your reply. I don't think this really has anything to do with it because of the following
1 - I have already removed every job and started with a clean sheet prior to posting the issue
2 - I also refreshed all the various pages and rebooted the machine from a fully turned off state, again prior to posting the original issue.
But for the record, I tried this again.
The Transporter hangs on refreshing at 40% and the Inventort error keeps coming back when I cancel it.
I think I really need to get in at the cmd level and force kill/remove the invetory and transporter.
