You can decrypt your AxCrypt 0-encrypted files with AxCrypt 0. Just sign in to AxCrypt 0, and select "decrypt". If your AxCrypt 0 password is not the same one used to encrypt the file, you will be prompted for the original password. If you have forgotten the password used to encrypt the original file, then you can't decrypt. Please read the FAQ at https://forum.axcrypt.net/ .
