Well, I feel like I’ve wasted your time, and my apologies for that – I originally tried 3 different web browsers (Chrome, Firefox, Edge) – however after digging out the classic IE, I was able to get past the startup screens, and can no login on other browsers. I wish I’d gone back to IE for a try before messaging you. If the reason for the reset to defaults pops up again, I’ll have to come back to troubleshoot it. Thank you.
