Well, I was missing the AmazingCharts.xml file a few different occasions (I believe staff was deleting it and permissions were not in effect to stop them) and once I recreated the .xml by hand, and a separate time I opened AC and it did not find the database, and so I closed out and tried again, and it prompted me to start the Amazing Utilities and I ran "Repair" which replaced the AmazingCharts.xml. I guess I should have mentioned that it was the Repair in Amazing Utilities that fixed the problem, not sure why I didn't. Maybe because it's Monday!?
