I have updated the SMF Importer and you can download the latest again via the same links in my original post above.
Fixed:

• Forum parent hierarchy
• Imported Replies now import correctly
• User Display Name

Outstanding:

• User Passwords
• Custom BBCode for Topic & Reply Content

NOTE: If you are importing ‘users’ during the import you will see multiple instances of the following two error messages:-

• Notice: Undefined variable: user_pass in /home/webhost/public_html/wp-includes/user.php on line 1305
• Notice: Undefined index: salt in /home/webhost/public_html/wp-content/plugins/bbpress/includes/admin/converters/SMF.php on line 566

These can both be ignored and only relates to the current non-working state of converting user passwords. If you need to login (or users login) they will just need to reset their WordPress password to be able to login.
