I have a similar but slightly different problem. I used Ascrypt to encrypt some of my files; I’ve been using it for years, so I’m sure it was an older version of AxCrypt. I have no real security issues, so I used a really easy-to-remember password. Then my coputer crashed. I needed to do a clean reinstall of the OS, so that meant downloading AxCrypt again. I was prompted for a password and gave it the password I’d used to encrypt all those files. I got an error message — apparently that password was too easy to break — so I created a new one. Now I can’t decrypt my files!
