Just installed and allready getting DB error

[محروم.كوم]

I have installed vbulletin and I get a vbulletin database error.
I have reinstalled it twice.

When I go to the admin section and click options the database error appears. Can someone help me?

This is the error I get inside my email:

Database error in vBulletin 3.8.4:

Invalid SQL:

SELECT setting.*, settinggroup.grouptitle

FROM settinggroup AS settinggroup
LEFT JOIN setting AS setting USING(grouptitle)
WHERE settinggroup.displayorder 0
ORDER BY settinggroup.displayorder, setting.displayorder;
