Cannot convert from phpbb3 to smf due to various errors, please help!

[grtt]

Hello,

After 15 years of using phpBB I've decided to move to SMF. So I've installed the converter to convert a phpBB 3.0.12 to SMF 2.0.15.
The first error I got when starting the converter was Unknown system variable 'SQL_MAX_JOIN_SIZE'. I found a solution here, saying that I should delete some lines at the converter.php file.
Then the converter starts and after saying Converting ranks.... nothing happens! It just stays there. By browsing the error.log file I got the following errors:

PHP Notice:  Undefined property: mysqli_result::$EOF in .../convert.php on line 2688
PHP Notice:  Undefined property: mysqli_result::$Fields in .../convert.php on line 2692
PHP Notice:  Trying to get property of non-object in .../convert.php on line 2693
PHP Fatal error:  Call to undefined method mysqli_result::MoveNext() in .../convert.php on line 2698

the latter being the fatal one.

Any idea of what's going wrong?

Try using SMF 2.0.13 then run the convertor.

Where can I find older versions to download?
