Cannot create new style

Think I broke my styles, I am unable to create a new style, when I try I get this message.

You can't parent a %1$s to one of its own children.

This happened after I deleted some styles then tried to import the style.sql to restore them, that was a bad idea as my forums just showed with images missing.
So I deleted all the styles via phpmyadmin apart from the 1st style and that got my forums back but now I cannot create a default vBulletin style.

Fixed, needed the database style id settings changing (Auto increment was off)
