PwManager mangled for good

This might seem an unusual problem, but... Long ago (back to FC4), I started using the PwManager program. I kept it up to, I believe, version 1.2.4 (Lilli) for F11. Today, at long last, I cannot get it to start. Repeated attempts to start it have failed. I have a lot of passwords for a lot of accounts. And if I cannot somehow resurrect this program, I have lost them all. The only hope is: anything held in the Thunderbird or Firefox password managers, is still there. I checked. But sometimes, those passwords get lost and do not propagate to a sign-in. As it stands, I'm going to be drawing a lot of unwanted attention to myself by sending password lost/changed requests. How can I avoid this? And can anyone recommend a good password-management solution other than a handwritten Little Black Book of passwords? Temlakos
