Migration phpbb2.0.18 to SMF 1.0.6 impossible

[Zedification]

SMF Version: SMF 1.0.6
Hello, During the migration I have this message:

Warning:  mysql_fetch_assoc():  supplied argument is not has valid MySQL result resource in/var/www/sdb/f/4/***/***/phpbb2_to_smf.php one line 124
Warning:  mysql_free_result():  supplied argument is not has valid MySQL result resource in/var/www/sdb/f/4/***/***/phpbb2_to_smf.php one line 125

Follow-up of: 

The installation of SMF in the path you specified is not a version this converter can deal with. If it is older than SMF 1.0, you need to upgrade first. If it is newer, you need to use a different converter.

I used a script (phpbb2_to_smf.php) downloaded on the official site of SimpleMachine. 

My provider is Free.
I already do some research, without success!

Thank you for your assistance
