Mybb 1.4 to SMF 2.0 rc2 problem

[Mirelo]

When i try to convert mybb to smf i get this error:

What i have to do?

Can you please try, just in case, to run the convert script from the SMF directory, and have the mybb file there as well?
Also make sure you restart the conversion fully, like writing http://your_smf_forum/convert.php with nothing else, no parameters in the URL.
