I remember the password i placed on the wallet.
strangly enough i downloaded hex editor and went through to find the private keys but had no success.
good chance because it was created with 5.18 multibit classic.
the encoding is different.
im also unable to find the hex value with the screen shot provided.
Those instructions won't work if there is a password on the wallet. If there's a password on it then its contents are encrypted (scrambled). If it's encrypted you can't read the private keys inside the wallet, or see the sequences of bytes that precede them.
