Ok, so you have AxCrypt 2 installed – but you tried to decrypt using “AxDecrypt” which can only decrypt version 1 files, and thus will fail with the message “New file version – cannot decrypt“. Use AxCrypt 2 for these files.
Ok, I misunderstood the following you wrote: “The last modified dates of the files (just 3 of over 50) I cannot access are dated a month after I installed the pc they now reside on and a few days before registering and installing axcrypt 2. ”
This says these files were encrypted using version 1, before installing AxCrypt 2. But the failure to decrypt them with “New file version – cannot decrypt” indicates that they were indeed decrypted at least once, and thus re-encrypted with AxCrypt 2.
Looking at the log files, it appears you actually *reset* your password 0n September 25 last year, after registering for AxCrypt 2 on June 10. So there is large gap in between where you may have use a subsequently forgotten password.
The “file password” requested is just that – AxCrypt asks for it when the sign in password does not work to decrypt the file. With default settings, any successful opening of a version 1 file will automatically re-encrypt it using the new AxCrypt 2 format and the then current sign in password.
When signing up for AxCrypt and starting the application, we give multiple warnings about the need to remember the password, and have a procedure where you are required to enter it at least three times before it is ever used to encrypt anything.
