I finally have the solution! My camera has been down for well over a year now. BeaverBoy sent me a Personal Message to suggest that I TENET into the cam and reformat it. Well I've not ever done that or used TELNET commands etc. It took me 14 months to get up the courage and find the time to try it.
I Googled TELNET to learn how to do it, and using the Format command I wiped out the troubled firmware. I then installed a previous, known to work without problems, firmware and I was able to save the camera!
